“…In addition all the observations made on the general aspect and the structure of the studied material, were also observed by San-Antonio-Gonzalezetal in his study led on a lightweight material made with gypsum and extruded polystyrene waste [7]. Wenbo and shi also showed that the expanded polystyrene particles adhere well to the cementitious matrix and even remained intact after the destruction of the samples [25].…”

“…The obtained results showed that the cement composites based on polystyrene aggregates presented acceptable mechanical strengths with excellent thermal insulation. Many attempts have been made in order to improve the mechanical strength of polystyrene concretes using the addition of fly ash, the increase of cement content, the addition of fibers, etc [6,7]. It should be generally noted that the use of expanded polystyrene has been mostly studied in the case of concretes.…”

Introduction:This study aims to highlight the physicomechanical properties of a new lightweight construction material which is composed of plaster as a binder and dune sand and Expanded Polystyrene Beads (EPS) as aggregates.Methods:For this purpose, different mixtures were designed with different percentages and particle sizes of EPS aggregates in order to test the porosity, the density and the thermo-mechanical properties of the studied composite. Furthermore, Electron Microscopy (EM) visualisation and SEM analysis were used for the study of the structure and the interface “paste-aggregates”.Results and Conclusion:The obtained results showed that the progressive incorporation of an increasing percentage of PSE decreases the density of the plaster composite and consequently improves its thermal properties. As expected, the mechanical strength decreases with the increase of the EPS content, but relatively good mechanical strength can be obtained with low quantities of EPS. Concerning the material structure, it should be noted that the composite appears more or less homogeneous and the EPS beads adhere well to the plaster matrix.

This article develops a relationship between the reduction of density in lightened gypsum and the addition of expanded and/or extruded polystyrene waste from the construction sector and their mechanical behavior. The equations determined in this study allow us to know the flexural and compressive strengths of a lightened gypsum/plaster compound once its density is known. The results show that there is an exponential relationship between the density of the compound and its strength. The methodology followed included a compilation of the results obtained in previous research works on lightweight gypsums, analyzing the relationship between density and mechanical strength and comparing them with the equations developed in this research. The results obtained by previous researchers have a good adjustment with the proposed models, and only perlite compounds present greater deviations in the compressive strength analysis. Also, a dimensionless lightening coefficient is defined which can help to determine the best application for a lightweight gypsum compound, comparing it with an ideal lightweight gypsum.
