USE OF POLYSTYRENE MATERIALS IN THE CONSTRUCTION OF BUILDINGS IN THE NORTH-CENTRAL REGION OF BURKINA FASO: ECONOMIC, SOCIAL AND ENVIRONMENTAL ISSUES

The acquisition of decent housing at lower costs is a major concern in Burkina Faso. Indeed, a largenumber of buildings are built in concrete and concrete blocks. This technique of building buildings with these materials is expensive and very energy-intensive, which poses an access problem for the majority of Burkinabe populations. In this research, we study the economic, social and environmental issues of building polystyrene buildings. Our study first focuses on the model of social housing adapted to the north-central region facing the housing problem caused by the displacement of populations fleeing areas with high security challenges. Then we carried out a dimensioning of the model of this building in polystyrene-based construction material. Finally, we carried out a comparative study between construction in polystyrene materials and construction in concrete materials.
