Secondly, due to the continuous mining of limestone for the production of cement there is also simultaneous depletion of natural resources and hardly will it last up to maximum 40 years. Hence we need to switch over to some other alternate binders for constructions purpose in future. Geopolymer Cement is one of the inventions which is produced by a polymeric chain reaction of alkali-activated alumino-silicate materials better known as alkali activator (NaOH/Na2SiO3) binders with the industrial by-product materials such as Fly Ash, Rice Husk Ash, Slag, Crusher Dust etc. and provides high compressive strength which is comparable to BPC and reduces the carbon foot print. The objective of our study is to prepare the low CO2 foot print green Geopolymer Cement which may substitute the Ordinary Portland Cement and Blended Portland Cement in future and will helpful to reduce the greenhouse effect up to some extent and takes an initiative towards the green revolution movement.</p> M.

It also concerns engineers from design offices and experts from offices responsible for diagnosing existing structures, as well as engineers from repair companies. Like all countries in the world, the study of the pathology and safety of civil engineering buildings is one of the big problems encountered in the field of construction in Algeria. The foundations are among of the structural elements of the buildings most affected by this damage, these constitute the link between the structure and the soil, they allow the transmission of loads from the structure to the soil. If these structural elements are damaged, they affect the general stability of the building. Depending on the severity of the damage, it can cause the building collapse. The main objective of this paper is to study a pathological case of foundation failure of a residential building: from diagnosis to reparation. This repair was carried out according to an intervention plan comprising stages spread over time, this allowed the strengthening of the infrastructure and gave the building an acceptable level of security.</p> A.

Prefabrication is the practice of assembling components of a&nbsp;structure&nbsp;in&nbsp;factories, and&nbsp;then transporting the&nbsp;complete assemblies or sub-assemblies to the&nbsp;construction&nbsp;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.&nbsp; 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.</p> Neha Gupta, Mohammad Arif Kamal , Tejwant Singh Brar Copyright (c) 2021 Journal of Building Materials and Structures https://creativecommons.org/licenses/by/4.0 http://journals.lagh-univ.dz/index.php/jbms/article/view/1054 Fri, 26 Feb 2021 20:55:37 +0000 Study of the mechanical behavior of dune sand treated by hydraulic binders: application in the road geotechnical field http://journals.lagh-univ.dz/index.php/jbms/article/view/1005 <p>The purpose of this work consists of valorizing a local sand dune which is found in abundance in the region of Djelfa (Algeria); for use in pavement foundations. For this investigation a method of formulation has been proposed, which based on the stabilization of this material using a mixture of two hydraulic binders. Various mixtures were subjected to classification tests, tests grain size distributions, tests of compaction with modified Proctor, shear strength, tests of bearing pressure (CBR unsoaked and soaked), compressive strength and tensile strength. The results obtained have shown that some mixtures are of high mechanical characteristics and could be then used in road foundations.</p> <p>&nbsp;</p> Ali Smaida, Smail Haddadi , Ammar Nechnech Copyright (c) 2021 Journal of Building Materials and Structures https://creativecommons.org/licenses/by/4.0 http://journals.lagh-univ.dz/index.php/jbms/article/view/1005 Mon, 22 Mar 2021 13:54:53 +0000 Numerical investigation to reduce environmental emissions from manufacturing industries http://journals.lagh-univ.dz/index.php/jbms/article/view/1053 <p>This paper aims to study carbon dioxide emissions from the cement manufacturing under wind conditions. These effects are investigated by Computational Fluid Dynamics (CFD) code used both method such as a Large Eddy Simulation (LES) and K-ε methods to investigate a spread of pollution in vicinity of manufacturing. The predicted concentration, velocity and temperature of CO<sub>2</sub> were used as the safety criterion to provide the useful information about a pollution amount resulted under variant environmental and structural conditions. A detailed look at results is beyond the scope of analysis to determine optimal CO<sub>2</sub> emission. From the present numerical simulation the&nbsp;carbon dioxide&nbsp;appears to be the best candidate as&nbsp;tracer gas and Simulation&nbsp;(LES)&nbsp;methods, which directly calculate the&nbsp;large-scale turbulent structures and reserve&nbsp;modeling offer the&nbsp;best&nbsp;analysis of turbulent flows.</p> Hadj Miloua Copyright (c) 2021 Journal of Building Materials and Structures https://creativecommons.org/licenses/by/4.0 http://journals.lagh-univ.dz/index.php/jbms/article/view/1053 Mon, 22 Mar 2021 14:13:24 +0000
