Authors: Oyedepo Olugbenga Joseph , Olukanni Ebenezer Omoniyi
Published: February 2022

Performance of non-conventional materials namely palm kernel shell (PKS) and periwinkle shell (PWS) were investigated. Sieve analysis, aggregate impact value (AIV), aggregate crushing value (ACV), bitumen penetration, Marshall Stability, flash and fire point were carried out in accordance with American Standard for Materials and Testing (ASTM) and British Standard (BS) specifications. A total of thirty-six samples were prepared by partially replacing coarse aggregate with PKS and PWS at 0%, 10%, 20%, 30%, 40% and 50%. The AIV and ACV values of 35.85% and 11.49% were obtained for PWS, while 6.42% and 9.22% respectively were obtained for PKS; this is usable for wearing course. The 10% partial replacement with PWS has Marshall Stability value of 2.33kN; 10% and 20% partial replacement with PKS has Marshall Stability values of 3.0kN and 2.2kN respectively, while 10%, 20% and 30% partial replacement with combination of PWS and PKS has Marshall Stability values of 3.22kN, 2.41kN and 2.21kN respectively; thus satisfying the requirement for light traffic road. Also, 10% and 20% partial replacement with the combination of PWS and PKS gives a flow value of 8.9 mm and 8.5 mm which can be used for light traffic. Hence, 10% to 20% partial replacement of coarse aggregate with PWS and PKS can be used as alternative material in asphaltic concrete to reduce the cost of construction.

Authors: Latreche Sihem , Sriti Leila
Published: February 2022

The building envelope is the first barrier to protect against external climatic variations. Generally, it consists of two types of walls: opaque walls (walls and roof) and transparent walls (Windows). The design characteristics of the enclosure strongly affect the occupants' thermal comfort, as well as the building energy consumption. The constructive choices relating to structural elements, in particular, walls, roofing and openings are generally considered in the thermal exchanges between the building and its environment. In the present study, which is based on experimental analysis in the self-generated residential sector in Biskra (Algeria), where a warm and arid climate predominates, we aim to evaluate the thermal impact of certain architectural and constructive parameters that are specific to residential habitat self-produced in Biskra. This paper summarizes the main results obtained from an in situ measurement campaign that evaluated the essential parameters of thermal comfort such as ambient and surface temperature, air velocity, and humidity. These parameters were used as indicators to measure the impact of the envelope material characteristics on its climatic adaptability. This paper also presents some recommendations for optimizing the choice of building materials specific to the self-produced residential in order to improve its thermal performance while preserving the essentials of its specificities.

Published: February 2022

Plastic waste recycling for the development of new building materials, such as cementitious composites, appears to be one of the best solutions to get rid of this type of waste. This operation has many economic and ecological advantages. The present study proposes some solutions for the recovery of plastic waste from PET (polyethylene terephthalate) bottles in order to obtain, after heat treatment at 290 °C followed by step cooling, a light composite material (PET-siliceous sand) with a hardness close to that of natural rock. The structure of the material obtained is characterized first; then the effect of this composite, with different substitution rates of natural aggregate, on the behavior of an industrial screed is studied. Afterwards, some specific recommendations for the uses of this screed, and possibly of the composite itself, are given. Although the main effects of certain polymeric additives on the mechanical properties of mortars are known, the mechanisms that are responsible for these effects are not yet well understood. Techniques such FTIR, XRD, SEM and differential scanning calorimetry (DSC) are analytical tools that can be used for the characterization and expertise of this type of composites, particularly the industrial composite screeds. Results from the present article enabled us to state that the composition of the materials obtained remains qualitatively unchanged and that no chemical interaction was observed between the mineral species and the waste PET lightweight aggregate (WPLA) or the composite itself; in fact, no new compounds were formed. In addition, the differential scanning calorimetry (DSC) technique allowed us to conclude that the addition of WPLA has an influence on cement hydration. The thermo-mechanical characterization of WPLA made it possible to observe an excellent arrangement between the PET and siliceous sand. Therefore, the development of WPLA may be another solution for a number of applications in the field of eco-materials for construction and building.
Comparative study and optimization of the mechanical behavior of sandwich beams loaded in three point bending
Authors: Bourouis Fairouz , Mili Fayçal
Published: February 2022

The sandwich material presents a certain interest in term of rigidity and specific resistance for the aeronautic structure design. The study of this material meets always the choice problem of their constituents (coating and core) in order to find the optimal mechanical characteristic. The aim of this work is to do a comparative study of the mechanical behavior of the sandwich beams loaded in three point bending. The structures considered consist of two skins of composite material with unidirectional fibers of six plies Glass/epoxy, Carbon/epoxy or Kevlar/epoxy of stacking sequence [0°/90°]3s and [45°/-45°]3s and the core is in Alporas , Corecel, PVC, or Polyurethane foams. The different results obtained from the Matlab code showed that the correct choice of the material of the coatings and of the core that improves the mechanical behavior of the sandwich beam. In order to increase the performance of sandwich beams, in three points bending, an optimization program based on the principles of genetic algorithms has been developed to maximize the tensile strength of face yielding and face wrinkling failure modes. The equations used to evaluate the individuals in population results from the classical laminate theory with transverse shear stresses and discrete variables. Operators of genetic algorithms (selection, crossover and mutation) are applied to the children of a hundred generations. To achieve optimal solutions, the result appeared effective despite all the non-deterministic nature of genetic algorithms. But, to achieve maximum effectiveness, it’s important to choose smartly the parameters of genetic algorithms depending on the nature of the problem studied and the mechanical characteristics of the function to be optimized.

Published: February 2022

In this study, we investigated the influence of the addition of sisal and glass fibres on the mechanical properties of polymer concrete (PC). These types of concrete are used in many modern civil engineering applications. The prismatic specimens sized according to ASTM C580-02 were elaborated with a PC constituted by 14% constant mass of polyester resin matrix, a granular skeleton based on sand and powder marble. The reinforcement with 60% sand and 26% marble powder adopted in this investigation is the best formulation found in previous authors work. This composition was reinforced by 1 and 2% of sisal and glass fibres, the first one having lengths of 6 mm or 12 mm, however, the second unidirectional cut into bands. These specimens were subjected to 3-point bending monotonic loading. The results obtained were discussed and compared with those obtained for control beams without fibres reinforcement. It is important to note that the incorporation of the glass fibre contributes to an increase of the ultimate load of the polymer composite material produced, however, the addition of the sisal fibre lead to its decreases. In addition, the incorporation of 2% of sisal fibre having 6 mm length leads to a reduction of 26% of the mass of the specimens.
Study of Architectural Ceramics of the Qal’a of Bani Hammad
Authors: Brahmi Abla , Hamiane Messaoud
Published: February 2022

In order to define with precision, the physicochemical characteristics of the architectural ceramic exhumed from the Qal’a of Bani Hammad’s site (inscribed on the UNESCO’s World Heritage List in 1980), our study was conducted on a set of ceramics. The first analyses were focused on the color of the glazes, by optical absorption spectrophotometry (also called optical absorbance spectroscopy), on the texture by X-Ray diffraction, and on the elemental composition of the various constituent stages of these glazes and their terra cotta, by scanning electron microscopy and X-Ray fluorescence. Indeed, the study combining optical absorbance spectroscopy and X-Ray fluorescence enabled us to determine the origin of the monochromic green coloring of the glazes in some samples. This coloring can be attributed to the presence of the Cu2 chemical element; but these glazes darkened due to the high iron content they contain. This could be explained by an intentional addition of iron, in tin-opacified leaded glazes, baked in an oxidizing atmosphere and put on a limestone-rich marlacious paste.

The chemical and mineralogical analyses of all shards show that their paste is calcareous. This dataset will be exploitable for re-creation experiments. It also represents a first exploitable referential system, for potential comparisons with other samples belonging to other Algerian sites and different periods of time.

Authors: Kazi Tani Nabil , Benosman Ahmed Soufiane , Senhadji Yassine , Taïbi Hamed , Mouli Mohamed
Published: February 2022

This present study aims to investigate the evolution of structural response of PET-Mortar composite test with a short-beam specimen in three-point bending tests, with composite mortar ages and volumetric polymer rate and this, based on compression strength tests. The ultimate PET-mortar composite structural responses are calculated at the mid span of the short-beam by the mean of mechanics-of-materials theory basis. According to this theory, the distribution of bending moments and shear forces at any point of the composite short-beam specimen doesn’t depend on material mechanical properties especially the young modulus of modified mortar composite; so, the structural response analysis has been limited to investigate the evolution of ultimate deflection with several volumetric PET rates and composite mortar ages. In the other hand, we present a comparative study between experimental test results of splitting tensile and compressive strengths with the ones predicted by codale previsions (ACI-363 and B.S) codes in terms of PET mortar ages and volumetric PET rates in order to recommend the most suitable design code for PET-mortar composite applications in construction industries.
An empirical enquiry into windows used in tropical office spaces
Authors: Gyimah Kwabena , Amos-Abanyie Samuel
Published: February 2022

Environmental health is very instrumental to the survival of the human race and there is the need for behavioural change for its quality. Grounded in literature is the fact that amongst all the elements of the building fabric, window is the only element which contributes holistically to Indoor Environmental Quality (IEQ). However, there is no certainty that building professionals or clients consider IEQ in the selection of windows for buildings and spaces holistically. This study seeks to evaluate the various types of windows mostly used in office spaces and establish the rational for their choice. Questionnaires in the form of Google forms were developed and sent to a convenient sampled population of architects and clients in Ghana. Results shows that none of the architects or clients choice of window had a holistic rational towards achieving all the variables of IEQ - thermal comfort, lighting quality, air quality and sound quality. Most of the choices by respondents were based on at least one of the variables of IEQ as a rational. In some cases, the rational of clients had no link to IEQ. Both clients and professionals suggested modifications to current office windows for better IEQ. It is also recommended that further research is carried out to validate the findings. The relevance of this study cannot be down played as knowledge is acquired for re-engineering of appropriate and holistic window towards IEQ.

Authors: Belarbi Mohamed-Ouejdi , Tati Abdelouahab , Khechai Abdelhak
Published: February 2022

The current work investigates the effect of thickness stretching on the natural frequencies of laminate-faced sandwich plates using new layerwise finite element model. The proposed model assumes higher-order displacement field for the core and first-order displacement field for the face sheets. Thanks for enforcing the continuity of the interlaminar displacement, the number of variables is independent of the number of layers. The consistent mass matrix and the element stiffness matrix are derived using the Hamilton’s principle. The performance and reliability of the proposed formulation are demonstrated by comparing the author’s results with those obtained using the three-dimensional elasticity theory, analytical solutions and other advanced finite element models.

The latest earthquakes history shows that resistant conception, safe and economical structures are a daily challenge for structural engineers. Among the newest vibration control devices figures the inerter which is a device which can develop a large fictive mass (it consists of a mass amplification effect) using rotational inertia. In this research work, the effectiveness of a traditional passive tuned mass damper (TMD) is compared with a tuned mass damper inerter (TMDI) which consists generally of tuned mass damper coupled with an Inerter. Both devices are used to control a base-isolated structure vibration submitted to several seismic records. In This study, a base-isolated structure of six stories (6 DOF) was equipped with (TMD) and (TMDI) and a time history analysis were performed under different earthquake records (El Centro, Kobe, Kocaeli). The mathematical model of the building is established in MATLAB Simulink. The simulation results illustrated he robustness, performance and effectiveness of the structure equipped with a (TMDI). The dynamical parameters of interest were base and top displacement as well as the base shear force and peak inerter force produced.

A MSSS bridge with restrainer cables and lead rubber bearings at the two abutments and intermediate bents located in North Algeria is selected according to RPOA for seismic design category 1 is considered in this study.  A detailed 3D nonlinear analytical model of study bridge subjected to three components identical seismic excitation including pounding elements, restrainer cables and bearing devices at expansion joints is developed. The nonlinear characteristics of theses boundary elements are represented by bilinear hysteretic models. Under strong seismic excitations, the large longitudinal displacements result the collision between bridge decks or even unseating of these decks at expansion joints of MSSS bridge. Finally, the study reveals among others that in order to prevent deck unseating resulting from restrainer failures and subsequent bridge collapse, particular attention should also be given to proper design of nonlinear characteristics of restrainers and bearing devices.

The main purpose of this paper is to examine the development and current status of prefabrication       techniques and their application in building construction and why its use is still limited in the housing sector in India and why prefabrication is not being used so far to provide affordable housing to all. Prefabrication is the practice of assembling components of a structure in factories, and then transporting the complete assemblies or sub-assemblies to the construction site where the structure is to be located. The important aspect is how much of a potential difference it can establish so that appropriate development can be implemented. This paper reviews the current prefabrication system scenario for housing in India. The paper begins with a brief introduction about different types of prefabrication system. Subsequent topics address the need of prefabrication and ethical dilemma of technology transfer for prefabricated building system in India.  In this paper, a qualitative descriptive evaluation research method has been used. The research methodology comprises of case studies, visual observation and data collection. Finally, two case studies around the world have been presented to validate and illustrate the various modern trends and application of design and construction methods of prefabricated building system in housing.
ANN modelling approach for predicting SCC properties - Research considering Algerian experience .Part II. Effects of aggregates types and contents
Authors: Sahraoui Mohamed , Bouziani Tayeb
Published: February 2022

The objective of this investigation is to illustrate the effect of aggregates types and contents on fresh and hardened properties of self-compacting concrete (SCC) considering Algerian experience. Based on experimental data available in the literature, Artificial neural network (ANN) models are established to illustrate the variation of aggregate types and contents (sand and gravel) in binary and ternary contour plots. Modelling results concerning the effect of sand types and proportions in binary and ternary combinations show the beneficial effect of river sand (RS) and crushed sand (CS) on slump flow. The highest L-Box ratio was obtained for mixtures composed of 50% of both RS and CS for binary and ternary mixtures. The increase in CS content enhance static stability, while the increase in RS gives higher compressive strength at 28 days. Concerning the study of aggregate sizes and contents, it was found that the increase of sand content leads to an increase in flowability and a decrease in static stability. An increase in gravel content leads to a decrease in passing ability, while a significant improvement in viscosity, static stability and mechanical strength with an increase in gravel content were observed.

A Socially Non-inclusive Urban-Regional Development in Mexico: The Macrocephalic Growth of Mexico city in the Center Region
Authors: Pineda Octavio Luis
Published: February 2022

Under the basic premise that an economy and its territory as a socioeconomic entity, are inscribed into a nation’s space. Accordingly, the concomitant sustainable handling of its natural resources and people ́s well- being depends on myriad factors among which stands out firstly, the country's own socioeconomic dynamics and secondly, but not least important, the political capacity of the State ́s intervention into the economy, as the foremost legal entity capable and social risponsible to advance the nation ́s economic strategy, to promote simultaneously growth and social well-being into the nation. Upon this framework, the article aims at analyze the socioeconomic implications of the neoliberal economic strategy adopted by Mexico, with particular reference to Mexico City (CDMX) vis-à-vis Mexico’s Center Region (encompassing CDMX and neighboring states) to demonstrate its failure and the compelling need to it towards a more balanced, social-inclusive and sustainable one. Time ́s horizon for the analysis ranges from 1980-2020e.
The Heroic Code and the Challenge of Time in Beowulf
Authors: Rois Robert
Published: February 2022

In this study we endeavor to explain significance by viewing the hypothetical statements. Recurring syntactic units in a text, such as “if clauses,” allow us to decipher meaning by relying on rhetorical semantics. We combine the social, religious and political roles of the Homeric Zeus with basic notions for evaluating behavior in primitive warring societies. The roles of Zeus as protector of guests, suppliants, and those laboring under the sworn word, yield as paradigms the categories of boast, prayer, and oath. Opposing binary structures generate from these categories as challenge, curse, and betrayal respectively. We may classify as a heroic code the combined non-truth conditional statements that define or approximate equivalence to each one of the mentioned categories. Oscillation between positive and negative correspondence leads to character motivation and plot development in Beowulf. The reader is left to interpret conceptually the relevant symbolism, drawn from the hypothetical expressions, which commit the decision to act to a narrative dimension. We close our study with a suggestion that eager attempts to extend the will in time may inevitably fail, even ina predetermined heroic context.

Standar pendidik atau tenaga kependidikan merupakan salah satu strandar dari standar pendidikan di Indonesia. Standar pendidik dapat menentukan kualitas yang dihasilkan dari pembelajaran yang dilakukannya. Dalam menentukan kualitas pendidik maka harus ada penilaian terhadap kinerja guru. Penilaian kinerja guru biasanya dilakukan oleh Kepala Sekolah dan Ketua Yayasan, hal tersebut menimbulkan terjadinya penilaian secara subjektif. Untuk itu dibutuhkan sebuah sistem yang menunjang keputusan untuk menentukan kualitas dari pendidik atau guru sehingga penilaian dapat lebih adil dan bersifat objektif. Sistem yang menunjang keputusan untuk menentukan kualitas guru ini menggunakan metode Simple Additive Weighting (SAW). Sistem ini berbasis web dan android yang dibuat dengan memanfaatkan seperangkat komputer yaitu laptop dan menggunakan bahasa pemrograman PHP dan Java serta menggunakan database MySQL. Sistem ini dapat melakukan kinerja guru yang melibatkan siswa sebagai responden untuk mengisi kuesioner penilaian kinerja guru. Dengan melibatkan siswa yang dalam hal ini sangat berkaitan erat dengan cara pengajaran dari guru yang bersangkutan dapat lebih mengetahui kualitas guru tersebut dan menghasilkan penilaian kinerja yang cukup objektif.

Lembaga Amil Zakat (LAZ) dalam mengerjakan tugas dan pokok fungsinya sebagai penyalur zakat infaq shodaqoh dan wakaf (ZISWAF), juga memberikan kepercayaan kepada  para donatur yang berdonasi yang membutuhkan sebuah bukti kwitansi. Dalam Pengajuan kwitansi para petugas penerima zakat masih mendata donatur secara manual dengan menulis di kertas kwitansi, sehingga dalam waktu validasi tidak efisien dan juga dilain waktu  bukti kwitansi bisa saja hilang.  Penelitian ini bertujuan untuk membuat  rancangan sebuah sistem yang dapat mengolah data ziswaf untuk pengajuan elektronik kwitansi. Sehingga  dapat mengurangi penggunaan waktu yang lama, membantu mengurangi terjadinya kesalahan input data, memudahkan para petugas untuk memvalidasi data dari donasi yang telah di terima oleh petugas LAZ sebelum data tersebut disimpan ke dalam database menggunakan Finite State Automata (FSA) agar data yang tersimpan sesuai dengan format yang ditentukan. Dengan adanya penelitian ini diharapkan membantu para petugas penerima ZISWAF dalam mengelola data donatur yang lebih professional, mengurangi kesalahan dalam pencatatan kwitansi dan bisa menghasilkan e-kwitansi yang sesuai dengan data donatur yang berdonasi.
