Débattre de la différence des sexes, de la politique et de l’inconscient (texte suivi des observations de Jacqueline Rose)
Authors: Mitchell Juliet , Bras Pierre
Published: September 2017

Juliet Mitchell répond à la lecture que Judith Butler fait de son livre Psychanalyse et féminisme . Dans sa réponse, elle commence par clarifier les termes de la discussion, montrant que l’intérêt de Butler pour l’hétéronormativité diffère de l’intérêt de Mitchell pour l’oppression des femmes. Cela les a conduites à utiliser des termes – plus particulièrement la formule « différence des sexes » –, de manières divergentes, et cela a entraîné confusion et incompréhension. Butler prétend que Mitchell identifie la différence des sexes avec le masculin et le féminin ; Mitchell soutient que ce n’est pas du tout sa perspective. Elle observe que le fait biologique d’être femme et la féminité psychique ne correspondent jamais pleinement. Ayant clarifié la signification et l’importance de parler de la « différence des sexes », Mitchell poursuit son dialogue avec Butler autour de quatre problèmes fondamentaux : la transmission intergénérationnelle de la culture et de l’oppression, la signification et le caractère variable de l’interdit inconscient, la relation entre l’inconscient et le désir, et comment formuler le devoir politique de lutter contre l’oppression des femmes.   Observations de Jacqueline Rose Dans sa réponse à la lecture que fait Judith Butler du livre de Juliet Mitchell, Psychanalyse et féminisme , Jacqueline Rose montre que le fait d’avoir un corps donne forme à la construction discursive sur le sexe à travers l’importance du fantasme. Il ne s’agit pas de dire que le fait d’avoir un corps dicte quelles significations une personne donnera à sa vie, mais que la création d’une distinction entre les hommes et les femmes évoquera toujours mais de façon fortuite l’anatomie. Nous ne pouvons donc pas uniquement nous occuper des limites discursives du sexe, mais on doit aussi examiner la variété des fantasmes qui peuvent être produits par l’importance universelle des différences anatomiques pour l’inconscient. S’appuyant sur ses propres recherches pour comprendre la controverse entre Butler et Mitchell, Rose compare la transmission de l’oppression des femmes à la transmission d’un héritage ethnique, remarquant qu’il est dépendant des contingences de la pratique culturelle et des façons contingentes mais plus durables dans lesquelles cet héritage est soutenu par le fantasme.
De « tout ce qu’il y a sous le ciel » à « l’Empire du milieu » : centralité chinoise et excentricité européenne
Authors: Dubois de Prisque Emmanuel
Published: September 2017

Au moment où le jésuite Matteo Ricci rencontre la Chine, au début du XVI e siècle, l’excentricité européenne, selon la définition qu’en a donné Rémi Brague, et la centralité chinoise, se trouvent dans un rapport de complémentarité qui a donné une forme spécifique à cette rencontre, loin du mythe contemporain du dialogue des civilisations.
De la recherche communautaire à la transformation sociale : l’exemple du projet ANRS-AERLI sur l’accompagnement et l’éducation aux risques liés à l’injection

Published: September 2017

La situation épidémiologique des usagers de drogue (UD), et tout particulièrement des UD par voie intraveineuse (UDVI), vis-à-vis du virus de l’hépatite C et du VIH appelle aujourd’hui à de nouveaux moyens de prévention et de soins. L’intervention d’Accompagnement et d’Éducation aux Risques LIés à l’injection (AERLI) issue des pratiques des acteurs de terrain en direction des UDVI a fait l’objet d’une évaluation à travers le projet de recherche communautaire ANRS-AERLI mené en partenariat étroit avec l’Inserm, Médecins du Monde et AIDES. Cette intervention communautaire consiste en une session éducative en face à face, basée sur une observation des pratiques d’injection permettant une réponse individualisée. Cette étude longitudinale ayant comparé un groupe d’UDVI exposé à AERLI et un groupe contrôle non exposé a permis de mettre en évidence l’efficacité d’AERLI non seulement en termes de diminution des pratiques à risque de transmission du VHC et des complications cutanées, mais aussi à travers une amélioration de l’accès au dépistage VHC. L’intervention AERLI apparaît donc comme un outil supplémentaire à la politique de réduction des risques et un moyen d’inciter les UDVI au dépistage VHC à l’heure de l’accès universel aux traitements du VHC. C’est ainsi que deux changements majeurs ont été possibles grâce aux résultats de cette recherche communautaire, l’inclusion de cet outil pédagogique dans la loi de santé et sa visibilité dans le dernier rapport Dhumeaux sur les hépatites comme moyen d’améliorer l’accès au dépistage VHC.
Évaluation multicentrique de programmes d’échange de seringues en pharmacie
Authors: Beauvillier Emilie , Bonnet Nicolas , Cornibert Anne-Cécile
Published: September 2017

Introduction  : En France, les contaminations par le virus de l’immunodéficience humaine (VIH), le virus de l’hépatite B (VHB) et le virus de l’hépatite C (VHC) sont particulièrement présents au sein de la population des usagers de drogues par voie intraveineuse (UDVI). Les programmes d’échange de seringues en pharmacie (PESP) ont été développés pour permettre d’améliorer l’offre de matériel d’injection stérile gratuit auprès des UDVI, limiter les risques infectieux (VIH, VHC) et favoriser l’orientation de UDVI vers le système de soin. Méthode  : Différents questionnaires ont été mis à disposition des officines et des usagers de drogues afin de recueillir leurs pratiques, investissements, ressentis à l’égard des PESP. Des entretiens ont été réalisés avec les structures porteuses des PESP ainsi qu’avec des officinaux appartenant au programme. Résultats  : Les pharmacies appartenant à un PESP sont plus enclines à orienter un usager de drogues vers une structure de soins. Les pratiques de partage du matériel d’injection sont quasi nulles et sont moins fréquentes que les pratiques de réutilisation. Plus de la moitié des injections sont réalisées dans des conditions plus sécurisées avec des seringues propres. Discussion-Conclusion  : Le PESP constitue un vecteur de réduction des dommages liés aux injections et un vecteur d’entrée dans le parcours de soins tout en permettant l’amélioration des relations entre les usagers et les pharmaciens.
Acceptabilité et techniques d’appropriation par les usagers des outils de réduction des risques liés à l’injection – évaluation du Steribox ®
Authors: Jauffret-Roustide Marie
Published: September 2017

Afin de prévenir les contaminations par le VIH et l’hépatite C, le ministère de la Santé met à la disposition des usagers de drogues du matériel stérile d’injection dans le cadre de la politique de réduction des risques, et notamment le kit « Steribox ®  ». Afin d’évaluer le Steribox ® ainsi que les outils qui le composent, un module « Kit d’injection » a été intégré à l’étude ANRS-Coquelicot. L’objectif principal de ce module était de mesurer l’adéquation du Steribox ® aux besoins actuels des usagers de drogues, seize ans après sa mise en circulation. Cette évaluation a ainsi permis de mesurer le degré d’utilisation du Steribox ® ainsi que les raisons de la satisfaction ou de l’insatisfaction des usagers, dans une perspective d’amélioration des outils de réduction des risques. Les commentaires libres recueillis auprès des usagers ont permis de révéler les enjeux de l’acceptabilité des outils de réduction des risques, et en particulier le décalage entre les normes sanitaires et les modalités d’appropriation profanes.

Published: September 2017

Many natural and man-made disasters require the assistance from teams of health care professionals. Knowing that continuing education about disaster simulation training is essential to nursing students, nurses, and emergency first responders (e.g., emergency medical technicians, firefighters, police officers), a university in the northeastern United States planned and implemented an interprofessional mass casualty incident (MCI) disaster simulation using the
Project Management Body of Knowledge
(
PMBOK
) management framework. The school of nursing and University Volunteer Ambulance Corps (UVAC) worked together to simulate a bus crash with disaster victim actors to provide continued education for community first responders and train nursing students on the MCI process. This article explains the simulation activity, planning process, and achieved outcomes.

O posicionamento da aristocracia galega nas crises sucessórias da segunda metade do século X no reino de Leão (951-982)
Authors: Alexandre Sousa José
Published: September 2017

Este artículo tiene como objetivo analizar el papel de los miembros más importantes de la aristocracia gallega en los varios episodios de la sucesión real entre la muerte de Ramiro II (951) y la consagración real de Vermudo II en la catedral de Santiago en 982. Este período marca de uma forma indeleble capacidad política, social y militar de los miembros de las Casas condales galegas em un ambiente de grande degradación de la autoridade real, en disputa con la aristocracia de las otras geografías que formaban el reino asturleonés. Vamos a ver, a través de una mirada cercana a las fuentes escritas, el documental y narrativas, que lo que más llama la atención es la ambigüedad del posicionamento de los diversos condes em en relación a los diversos momentos de tensión con los miembros de la monarquía. Esta ambiguedad se basa en la dependencia del monarca para el mantenimiento y posible aumento de sus respectivas propiedades y privilégios, en un contexto de regresión territorial proporcionada por la dinámica musulmana implementado por el hachib del califa Hisam II, Abu Amir.

[gl] Neste artigo pretendemos analisar o papel dos membros mais relevantes da aristocracia galega nos diversos episódios da sucessão régia entre a morte de Ramiro II (951) e a sagração real de Bermudo II na catedral de Santiago em 982. Este período marca de forma indelével a capacidade política, social e militar dos membros das Casas condais galegas num ambiente de franca degradação da autoridade régia, em disputa com a aristocracia das outras geografias que compunham o reino astur-leonês. Iremos observar, através de um olhar atento das fontes escritas, documentais e narrativas, que o que chama mais à atenção é ambiguidade do posicionamento dos diversos condes em relação aos vários momentos de tensão com os membros da monarquia. Essa ambiguidade assenta na dependência em relação ao monarca para a manutenção e eventual aumento das respectivas propriedades e privilégios, num contexto de regressão territorial proporcionado pela dinâmica muçulmana implementada pelo hachib do califa Hisam II, Abu Amir.
Reyes, nobles y frontera. Entre la violencia y el parentesco en el espacio fronterizo galaico portugués (siglos XII-XIII)
Authors: Calderón Medina Inés
Published: September 2017

El nacimiento de la frontera galaico portuguesa fue un proceso complejo, pues dependió en gran medida de la capacidad de los monarcas de atraer a los nobles a su servicio y controlar el espacio. A través del análisis de las fuentes cronísticas y diplomáticas se examinará el comportamiento de la nobleza local en la definición y defensa de la frontera. Las fuentes muestran un gran protagonismo nobiliario en la guerra y en la paz en el sur de Galicia, así como las consecuencias de su fidelidad o traición. Pero además de atraer a la nobleza a su causa, los reyes intentaron solventar los conflictos fronterizos a través de los matrimonios regios, que conllevaban la entrega de los castillos y tierras en litigio como arras de las reinas de León. Ciertos nobles fueron elegidos para materializar los acuerdos matrimoniales, pues actuaron como garantes y árbitros entre los monarcas.

La translatio de los Santos Mártires de Braga a Compostela. Reflexiones sobre el capítulo I, 15 de la Historia Compostelana
Authors: Fandiño Fuentes Rafael
Published: September 2017

Braga, diciembre de 1102. En el transcurso de una aparentemente inocente visita pastoral a las posesiones que la iglesia compostelana tenía en la zona norte de Portugal, Diego Gelmírez se hacía con un importante número de reliquias, despojando a aquellas tierras de sus celestiales protectores. El suceso, calificado de “robo” por algunos autores portugueses, aparece definido sin embargo como “pío latrocinio” en el capítulo I, 15 de la Historia Compostelana, escrito poco tiempo después de los hechos que narra. Basándose precisamente en el contenido de dicho capítulo, e incidiendo en aspectos tales como su autoría y cronología, el presente trabajo pretende ofrecer al lector una reflexión sobre algunos elementos del relato que, en principio, han pasado inadvertidos a los ojos de la crítica. Al mismo tiempo, se intenta hacer una aproximación a los motivos que pudieron haber llevado a Gelmírez a actuar como finalmente lo hizo, según un modo de proceder que, por otra parte, no era algo excepcional a aquella época.

La Tierra de Lemos, en el sur de la provincia de Lugo, protagoniza una larga evolución desde los Lemavos prerromanos, en la que se ha ido adaptando a las diferentes realidades y episodios históricos. Dentro de este desarrollo, los siglos de la Plena Edad Media marcan un punto de inflexión: la fundación del burgo de Pino, después villa de Monforte, su nueva cabecera comarcal. Con este nuevo referente urbano, una tierra marcadamente rural y agraria recibe una nueva realidad morfológica, económica y social. Paralelamente, el conjunto de Lemos conoce un nuevo agente de poder: el concejo monfortino. Éste viene a unirse a los otros dos poderes locales: el monasterio benedictino de San Vicente del Pino y la nobleza laica, la de los condes en / de Lemos, llamados a ser la más importante casa nobiliar gallega de la Baja Edad Media. Los tres poderes juntos, en continua pugna, marcan la estructura y dinámica de la nueva villa, sobre la cual la corona ejercerce un cierto rol de balanza, inclinandola hacia un lado u otro con sus concesiones y prebendas.

Las fortalezas son uno de los más prominentes hitos del paisaje bajomedieval gallego. Pambre (Palas de Rei) es una de ellas, envuelta en la fama de ser una de las pocas capaz de resistir el ataque irmandiño. Sus constructores son los Ulloa, uno de los linajes nobles gallegos más distinguidos de los últimos siglos del medievo. La fortaleza de Pambre, convertida en el nuevo solar principal de la familia, tendrá un importante papel en los conflictos en los que se ve inmersa la casa. El objetivo de este trabajo es sistematizar la variedad de funciones que desempeña una fortificación señorial a partir de la bibliografía y las fuentes conocidas, tomando como ejemplo el caso de Pambre.

Peregrinación, pasado y presente. Perspectiva noruega con especial atención a Santiago de Compostela
Authors: Jensen Roger , Morten Løvrød Hans
Published: September 2017

En este artículo se analiza el fenómeno de la peregrinación a Santiago de Compostela como lugar santo y meta de peregrinaciones desde una perspectiva noruega. Además, la transformación de su papel y significado queda más claro desde un punto de vista histórico. En la época medieval, Santiago era una importante meta de peregrinación para los habitantes del Norte de Europa. Tras la reforma protestante y la division religiosa de Europa, Santiago ejemplificó los problemas y rechazos relacionados con las peregrinaciones y el mismo nombre de la ciudad se convirtió en algo peyorativo. Teniendo presentes estos antecedentes, se analiza el redescubrimiento actual de la peregrinación en Noruega y el papel que juega Santiago de Compostela como máximo ejemplo del renacimiento de las peregrinaciones en el mundo posmoderno actual. Se sostiene que la “rehabilitación” de Santiago y el nuevo interés por las peregrinaciones en Noruega han sido posibles gracias a la redefinición del concepto, que se ha dado a un nivel que podríamos considerar ideológico y se basa en recientes estudios empíricos del ámbito de las ciencias sociales realizados sobre el Camino de Santiago.

Published: September 2017

O objetivo desse trabalho foi analisar concepções de educação e pobreza presentes em materiais publicados entre 2006 e 2014 que falam diretamente aos beneficiários do Programa Bolsa Família (PBF). A pesquisa foi pautada no pressuposto de que os dizeres são constituídos por aspectos materiais, culturais, históricos e sociais. As publicações trataram a pobreza por múltiplas dimensões, tais como falta de acesso à alimentação saudável e negação de direitos. A educação foi reconhecida como importante instrumento para a superação das vulnerabilidades socioeconômicas. O gênero discursivo dos materiais possui caráter prescritivo e disciplinador, aspecto que foi perdendo força ao longo das publicações.

Effect of hydraulic retention time on hydrodynamic behavior of anaerobic-aerobic fixed bed reactor treating cattle slaughterhouse effluent
Authors: Freitas Daiane Cristina de , Passig Fernando Hermes , Kreutz Cristiane , Carvalho Karina Querne de , Arantes Eudes José , Gomes Simone Damasceno
Published: September 2017

The study of the hydrodynamic behavior in reactors provides characteristics of the flow regime and its anomalies that can reduce biological processes efficiency due to the decrease of the useful volume and the hydraulic retention time required for the performance of microbial activity. In this study, the hydrodynamic behavior of an anaerobic-aerobic fixed bed reactor, operated with HRT (hydraulic retention time) of 24, 18 and 12 hours, was evaluated in the treatment of raw cattle slaughterhouse wastewater. Polyurethane foam and expanded clay were used as support media for biomass immobilization. Experimental data of pulse type stimulus-response assays were performed with eosin Y and bromophenol blue, and adjusted to the single-parameter theoretical models of dispersion and N-continuous stirred tank reactors in series (N-CSTR). N-CSTR model presented the best adjustment for the HRT and tracers evaluated. RDT (residence time distribution) curves obtained with N-CSTR model in the assays with bromophenol blue resulted in better adjustment compared to the eosin Y. The predominant flow regime in AAFBR (anaerobic aerobic fixed bed reactor) is the N-CSTR in series, as well as the existence of preferential paths and hydraulic short-circuiting.

Simulation of Power Efficient Cooling Technology for Continuously Cast Bars
Authors: Demidenko L.L.
Published: September 2017

The article describes a power efficient technology, allowing to preserve and maintain the heat content in a continuously cast bar at the production line “Continuous Casting Machine – Rolling Mill”. It considers a possibility of obtaining the maximum heat content in the continuously cast bar by means of rational cooling schedules in the secondary cooling zone. In order to maintain the achieved heat content in the bar, it is proposed to utilize heat insulation of the bar in the air cooling zone prior to its cutting-to-length. The article describes the design of the heat insulating shell in the CCM process scheme and the materials to be used for it. To analyze the interaction of heat flows between the bar and the shell in the heat insulation zone, the author has made a thermal balance of this zone. A mathematical model of the concast bar cooling with due consideration of the heat insulation zone and its implementation by means of numerical methods is described here. The application of numerical simulation has allowed to predict rational cooling schedules for the continuously cast bar and to determine the heat content of the bar at the exit from the continuous casting machine with respect to the heat insulation. According to the results of the simulation, there have been plotted the charts of temperature distribution along the CCM length, comparing the air cooling of the bar and its thermal conditioning in the heat insulation zone. These results confirm the effectiveness of utilizing heat insulation for maintaining the maximum heat content of the bar, which makes it possible to reduce the power costs for its heating prior to the rolling.

There is experience of the production and use of low density autoclaved aerated concrete. It is shown that fly-ash from Reftinskaya State District Power Plant efficiently substitutes the quartz sand aerated concrete technology. Its use opens up additional opportunities for AAC with the density of 300-400 kg/m3. In order to optimize the structure and properties it has been suggested to introduce the gypsum aerated concrete additive into the autoclave in the amount of 3-5% by weight of the dry components. The introduction of gypsum ensures the creation of a uniform homogeneous structure, resulting in the increased strength properties and reduced drying shrinkage. The resulting aerated concrete has thermal conductivity of 0.075-0.100 W/m·K, it allows using and creating single-layer fencing structures without additional insulation. The low-density gas-ash concrete production allows extending the scope of cellular concrete application and increasing its competitive advantages over other walls and insulating materials.

Published: September 2017

The results of experiments aimed at obtaining multi-component coatings, having a wider range of properties compared to single-component coatings, are provided. The process of formation of coating based on multi-component alloy Co (18...20%)-Cr (5...7%)-Al (0.3...0.4%)-Y(0.2...0.5) was studied. The chemical composition and thickness of the coating as well as the state of the transition layer were also studied. The results of electron probing and X-ray fluorescence microanalysis of obtained coatings are provided. This paper also demonstrates that the properties of surface microrelief are determined by the conditions of coating formation; that each sample of coating has similar sets of chemical elements, that their concentration depends on the precipitation conditions, chemical elements are equally distributed along the thickness of samples, and the diffusion zone of coating materials and substrate is almost non-existent. The low content of substrate material was found in obtained coatings. As the coating thickness increased, the content of substrate material decreased sharply.

Magnetic nanomaterials play an important role in emerging industries, specializing in the study of objects (natural or artificially synthesized) with nanoscale building blocks. The wide use of magnetic nanomaterials (especially for biological applications) is constrained by the following reasons: difficulties in obtaining monodisperse ferromagnet particles with stable reproducible characteristics, high cost of large-capacity production However, nanomaterials with magnetic properties are increasingly used in everyday practice. Some companies have already established the production of the first samples of nanomaterials. The time to conduct of a large-scale search for the ways of practical use of magnetic materials has come. Ferrofluids or so-called magnetic fluids are suspensions of magnetic nanoparticles stabilized with a surfactant, in liquid media. Magnetite and ferrites can act as the magnetic phase in the ferrofluids. The liquid phase is water or an organic liquid. The dimensions of the magnetic nanoparticles are 5-10 nm. The market supplied magnetic fluids contain mostly magnetite. Such magnetic fluids are used as a separation medium, polarized external inhomogeneous magnetic field in the gold mining industry to recover the fractions containing 90-97% native gold. A method for the preparation of a colloidal solution with a narrow distribution of magnetite particles according to the size by the heterogeneous condensation method according to R. Zigmondi has been developed. Condensation is carried out on seeds, which is brought into the solution of nanoparticles of magnetite. Getting monodisperse sol is achieved by injecting a concentrated solution of one component in a very dilute solution of another, with vigorous stirring (typically Veimarn). A method called "double additive" proposed G.J. Fleer and J. Lyklema is used to stabilize the sol. The method reduces to the fact that the source unprotected magnetite sol stabilizer is added to a certain volume of a colloidal solution of magnetite, on the surface of which stabilizer is physically and chemically sorbed.

Authors: Mastalygina E.E. , Popov A.A.
Published: September 2017

Binary and ternary composites based on isotactic polypropylene and low-density polyethylene in a wide range of ratios without and with filler content have been investigated. Micron-scale vegetable cellulosic components initiating biological degradation have been used as fillers for polymeric composites. The analysis of stress-strain behaviour of the composites has shown a non-additive dependency of elongation and tensile strength at break on blends composition. Based on this study results the composition and structure of polymeric phase of binary and ternary composites, as well as dimensional parameters of filler particles have a significant impact on stress-strain behaviour of the materials. The main regularities determining materials mechanical properties have been discovered, that, in turn, could be used for predicting service behaviour of composites under investigation.

Published: September 2017

The quality of heat-exchange tubes is one of the most important factors affecting the technical condition and the durability of steam generators at nuclear power plants. The combined influence of the aggressive environment and stresses in heat-exchange tubes during the exploitation of steam generators leads to corrosive cracking of tubes. This results from the residual stresses (RS) stretching tube walls. The production of heat-exchange tubes involves the following operations: boring and grinding hot-rolled pipe billet, cold rolling middle-sized pipes, heating, rolling final-sized pipes, straightening, electro-polishing the inner surface and burnishing the outer surface, checking the final quality. The operation modes of straightening and burnishing predetermine the residual stresses in pipes in the delivery state. The paper presents the results of the studies on the residual stresses and surface hardening caused by the finishing operations. The paper also shows the need for exceptions to the production techniques for heat-exchange pipes, i.e. a series of operations increasing tensile residual stresses.

Published: September 2017

In this paper described the possibility for using the copper nanoparticles as additives to lubricating oil. Copper nanoparticle has a decreased melting point and low shearing strength, therefore, the particles exhibit a high degree of slip. Adding copper nanoparticles to lubricating oil, can reduce the friction and wear of the friction surfaces, increase engine power, while reducing air pollution with an increase operating life of the engine. In this paper also described the liquid reduction process as a method for copper nanoparticle manufacture, which can be carried out without expensive special equipment. Generally in the process of gathering products – nanoparticles need to use the ultracentrifuge, and there is the phenomenon of aggregation of nanoparticles. In this paper obtained copper nanoparticles with dimensions of 30-80 nm without using the ultracentrifuge by adding organic solvent to a solution of the reduction reaction. Also presented the test results for friction and wear of the parts in the environment of the lubricating oil added copper nanoparticles. The experimental test results confirmed the theoretical assumption that copper nanoparticles improve the operational properties of the oil and reduce the abrasion of the surface of friction parts.

Regulation the Properties of Materials on Magnesia Binder
Authors: Zimich V.V.
Published: September 2017

Industrial waste pollution in the cities and the areas beyond them is a burning issue today. The only solution is recycling the by-products of primary production. Thus, the magnesia caustics are widely used in construction. However, their application is limited due to their high hygroscopicity. Many scientists were involved into the study of this problem justifying their achieved positive result by either using different types of sealers or introduction of fine composition active mineral additives into the binder. Moreover, all these studies mainly focused on the improvement of the water resistance of magnesia composites, while hygroscopic regulation was not significant. So it is important to study the process of environmental moisture accumulation in the pores of the magnesia material. When establishing the causes of the high hygroscopicity of magnesium materials, it was found that its value depends on environmental conditions (temperature, pressure and relative humidity); the specific surface area of magnesia stone; density of the sealer for magnesia binder; the chemical composition of various modifying additives and their influence on the properties of magnesia stone and materials based on it; the composition of the hydrated phases of magnesia stone with additives and without them; the presence of pores, their size and number in the structure of the stone; the surface charge of a magnesia stone. Studies have shown that high-strength water resistant chlorine magnesia stone in combination with modifying additives allows obtaining a composite material with hygroscopicity less than 2 %.
