title: Proposal to assess quality of life and wellbeing in urban green areas

description: Abstract The current panorama of urban problems highlights issues related to a diminishing and deteriorating quality of life in cities. In this context, green areas are important variables for the evaluation of urban life quality and wellbeing. Hence, the purpose of this study is to evaluate the quality of life of people, based on the perception of regular users of two urban parks in the city of João Pessoa-PB, northeastern Brazil, the Solon de Lucena Park (PSL) and the ArrudaCâmaraZoobotanical Park (Pzac). For this purpose, the authors developed the Wellbeing Index in Green Areas (Ibeav), a methodology proposed and adapted from the Urban Wellbeing Index (Ibeu) with indicators developed from the following dimensions: mobility and accessibility, urban environmental conditions, urban housing conditions, urban collective services and urban infrastructure. The results obtained for the Ibeav were 0.80155 for the PSL and 0.7716 for the Pzac, indicating good and average quality of life conditions, respectively. Hence, through the methodology applied in the two urban parks, it was possible to identify the dimensions and indicators that contribute to expand and/or reduce the quality-of-life index of the evaluated spaces.

title: Influence of detachment dimensions on the evaluation of ceramic tiles with infrared thermography

description: Abstract Infrared thermography is currently an important tool in building inspections, mainly in the identification and diagnosis of pathologies in mortar and ceramic coverings. In the case of the evaluation of ceramic tiles with infrared thermography, it appears many questions still remain regarding the behavior of Delta T, the main parameter used in the analysis of pathologies in thermograms, due to the influence of the type and dimensions of the pathological manifestations studied with this technique. This study evaluated the influence of the dimensions of the detachments of ceramic tiles in the thermographic evaluation. For this purpose, a masonry prototype with ceramic tile covering was built, where the presence of detachments was simulated, and then evaluated in an external environment in different solar orientations, during a four-day period in in three consecutive years. The results showed that the maximum values of Delta T in the thermographic inspection were obtained at the moments of maximum increase of the covering surface temperature in the four solar orientations. After the statistical analysis, it was concluded that differences in width and, consequently, in the defects’ area, are more probable to be detected, which facilitates the evaluation of the performance of facade systems using infrared thermography.

title: Excessive displacement in timber roof structures as pathology conditioners

description: Abstract The NBR 7190 (ABNT, 1997) assumes the mean value of the elasticity module to compression in the direction parallel to grain (E c0,m ) as being the representative for all roof structure bars. Due to the variability of woods, such methodology can result in displacement values higher than the limit defined by the standard, which can generate pathologies in the structure. In order to evaluate the influence of the use of E c0,m on the displacement calculation, experimental tests were carried out to obtain the mechanical properties of the wood species Sebastianiacommersoniana (Baillon) Smith & Downs. With the aid of numerical simulations and experimental values, three typologies (fink, bowstring and parallel chord) and two spans (10 m and 20 m) were analysed. Adopting E c0,m , the maximum loads for a displacement of L/200 were determined. After, random stiffness values were assigned to each element of the truss, measuring the maximum displacement of each model. In models where the modulus of elasticity was randomly assigned, superior arrows were observed in approximately 28% and 32% for spans of 10 m and 20 m, respectively. It may explain some pathologies that can be avoided with non-destructive pre-classification and the rational placement of parts in the most vulnerable areas.

title: Potential of cactos xique-xique mucilage as a surface treatment for compressed earth blocks

description: Abstract Buildings with earth walls have outstanding hygrothermal properties, which contribute to a desirable regulation between temperature and humidity of environments. However, this type of masonry is vulnerable to pathologies due to the action of rainwater. This paper evaluates the efficiency of using the mucilage of the xique-xique cactus (Pilosocereus gounellei) as a surface treatment for walls made of compressed earth blocks (CEB). The aim is to obtain a protective film against rainwater, but which is permeable to water vapour. The tests performed with cubic specimens, extracted from CEBs, allowed comparisons between the proposed treatment (TX), using different mucilage concentrations, and a commercial acrylic waterproofing resin (TR), using as control samples without any surface treatment (TC). The results of the water absorption by capillarity tests showed that the TX sample with 1:1 concentration had a similar behaviour to the TR sample, since after 60 minutes of testing, TR, TX1:1 and TC had a mass increase of 0.3 g/cm², 0.5 g/cm² and 1.4 g/cm² respectively. Water vapour permeability for TX1:1 was 5% higher than TR and 6% lower than TC. After heat and thermal shock tests on small walls, the TX1:1 samples performed satisfactorily.

title: The role of recycled aggregate segregation on the strength and durability of structural concrete

description: Abstract The great heterogeneity of construction and demolition waste (CDW) hinders its systematic use, leading to problems in its final disposal and in the continual extraction and use of non-renewable resources in concrete manufacturing. This heterogeneity derives primarily from the fact that manufacturers do not segregate the wide variety of CDW components during their processing. This paper analyses the need to segregate CDW into two different types - clay ceramics (red) and rocks and cement (gray) - and the consequences of using these materials as substitutes for natural coarse aggregates in structural concrete. Hence, different concretes were manufactured with 25, 50 and 100% CDW, using three types of waste: cementitious, ceramic and a mixture of both. The conclusion is that it is not necessary to segregate the waste from the recycling plant, since the results show that the concrete with cementitious aggregates and the one with mixed aggregates perform similarly. In addition, the use of CDW affects the characteristics of the concrete. Rheological and mechanical performance are parameters negatively affected by the use of waste. However, durability may improve with the use of recycled aggregates.

title: Application of MEPLWF: method performance evaluation of the Light Wood Frame construction system

description: Abstract One of the 17 Sustainable Development Goals (SDG) set out in this agenda, objective 11 is related to the search for more sustainable cities and communities. This study wishes to contribute in this effort, presenting a method application to evaluate the performance of light wood frame buildings in Brazil. The structure of the method used, named MEPLWF, is based on five dimensions, which involve criteria and sub-criteria that analyse technical, social, environmental and economic requirements to evaluate buildings. It allows the examination of the operating results of buildings and the discovery of performance-related problems. The proposed method was applied in a real case study in southern Brazil, during the pre-occupation phase of the building. As a result, the performance identified in the building was 94%, which is a high performance. The application of the method in this case study diagnosed points that should be reviewed by the construction company, such as items related to fire protection and safety, flexibility and adaptability of the building system, environmental plan, energy efficiency and Costs.

title: Morphological characterisation of Brazilian expanded clay lightweight aggregate using AIMS

description: Abstract Due to the excessively rounded shape of expanded clay, data related to angularity, sphericity and surface texture can help to understand the relationship of these factors with the properties of concrete in the fresh state, such as workability and fluidity. This research sought to characterize the expanded clay in terms of morphology and to compare it with the particularities of the conventional aggregate using the AIMS (Aggregate Imaging Measurement System) equipment. The results indicate that the morphological characterization of conventional coarse aggregates (B0 and B1) are presented with subrounded angulation and moderate sphericity in both particles, whereas the surface texture is rough and harsh, respectively for B0 and B1. For coarse aggregates of Brazilian AE 2215 and AE 1506, the morphological characteristics such as angularity and surface texture were defined as rounded and polished, respectively, in both groups. However, there was differentiation as to sphericity, which is high for AE 2215 and moderate for AE 1506. Compared to the group of conventional aggregates, the lightweight coarse aggregate of Brazilian expanded clay indicates more rounded particles, with medium-high sphericity and surface texture smoother.

title: Influence of densification of silica fume on the properties of cementitious materials

description: Abstract The silica fume is commercially available in densified form (DS) when subjected to particle agglomeration processing to reduce its volume during transport, or undensified (US) when that process does not occur. The purpose of this study is to evaluate whether the densification of silica fume can influence the properties of cementitious materials. With that purpose, the effect of replacing 10% of Portland cement CP V-ARI by US and DS was investigated. Compressive strength tests were performed on the microconcrete at 1, 3, 7, 14 and 28 days. To explain the mechanical behaviour of the microconcrete, X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersion spectroscopy (EDS) tests were performed on the cement pastes. Due the smaller particle size and the higher specific surface of the US compared to the DS, there was a change in the microstructure of the cement pastes. The US provided a higher consumption of calcium hydroxide (CH) and a lower calcium/silica (Ca/Si) ratio in the cementitious matrix, resulting in a higher compressive strength in the microconcrete with US compared to that with DS. The study concludes that US is more effective when used in the production of cementitious materials.
