“…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].…”

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.

Concrete is a good constructional material as it posses enough compressive strength for structural purposes, in spite of that concrete has some dis-advantages, one of these main dis-advantages is its high density (2300-2400) kg/m³ .Many trials were made to minimize its density in different ways. Recently Expanded Polystyrene (EPS) granules (98% air) were added to the concrete for this purpose. In this investigation the concrete density is reduced by adding polystyrene granules to the silica-fume concrete. Silica-fume was added for enhancing the concrete strength and balances the loss in concrete strength due to the inclusion of polystyrene granules .Test results show that the inclusion of silica fume to the concrete improves its strength for both normal concrete and concrete of EPS beads. It is concluded that structural concrete (Strength > 17 MPa) with EPS beads can be manufactured when silica fume is added to concrete.

“…There was set a task to produce heat-insulating polystyrene concrete of B0,5-B1 classes with average densities of 250-800 kg/m3. Any calculated composition was corrected during the solar thermal treatment, taking into account the influence of temperature and the degree of dilution of the polystyrene-concrete mixture on the forming structure [2,3,4]. The dosage of the components of polystyrene concrete was carried out for cement by weight, for quartz sand by volume and weight, for polystyrene, water and additives by volume.…”

The energy of solar radiation is a powerful energy reserve at the surface of the globe which is about twenty billion kW. This amount of energy is more than 100 times greater than the amount of necessary energy for the whole planet; besides the usage of this powerful energy radiator is not associated with polluting substances that pollute the planet. The usage of solar energy nowadays is very important, as the problem of using traditional energy resources is especially acute, because of their irreplaceability and increase in their cost. At the plants of the Republic of Kazakhstan for the industrial production of building materials today, a trend is outlined for the use of non-traditional types of energy, and mainly solar energy at the stage of heat treatment, where steam heating was traditionally used. In these researches, development in the direction of temperature treatment of polystyrene concrete was considered. The purpose of the research is the development and practical implementation of the technology of production of polystyrene using solar energy. The results of the conducted researches confirmed that the usage of solar thermal treatment methods for the thermal treatment of polystyrene concrete is effective in weather conditions for the southern regions of the Republic of Kazakhstan which refers to areas with dry and hot climatic conditions. Detailed studies of polystyrene concrete under high-temperature weather conditions have been carried out and introduced into production. The usage of heliotechnology for the production of polystyrene concrete improves the quality of manufactured products, also makes it possible to reduce the energy costs of traditional energy covered by the use of solar energy.
