Introduction: expanded polystyrene (EPS) concrete is an environmentally friendly material; however, its compressive strength is lower than traditional concrete, requiring the incorporation of materials that improve its compressive strength. This paper reports the effect of waste glass (WG) incorporation on the properties of concrete containing polystyrene as partial replacement of fine aggregate. Objective: to evaluate the effect of the incorporation of glass residues on the physical and mechanical properties of concrete made from polystyrene. Methodology: concrete was produced with 10 % by volume replacement of fine aggregate. Different EPS:WG volume ratio 1:0, 1:1, 1:2, 1:3 and 1:4 (volume EPS +WG = 10 % volume fine aggregates replacement) were prepared. The slump of fresh mixtures was evaluated, density and compressive strength of hardened concrete at 28 days was evaluated; the durability was assessed through alkali silica reaction test. Results: an increasing in glass content was inversely proportional to slump, additionally, with the incorporation of glass, the density was not significantly affected. The incorporation of waste glass greatly increases the compressive strength, being the EPS:WG 1:3 mixture that showed the highest compressive strength, which was 37.2 % higher than reference concrete (1:0) was. Additionally, in 1:3 mixture was evidenced that the addition of waste glass does not lead to deleterious alkali silica reaction effect. Conclusions: the addition of waste glass to concrete prepared from expanded polystyrene improved its mechanical properties, making it a potential system to replace traditional materials used in concrete production.

The article presents a bibliographic review on alternatives of low environmental impact for the recycling of expanded polystyrene worldwide, based on the use of natural resources and the environmental impacts associated with them. The environmental impact of each technique was determined through the construction of an Excel matrix where the frequency of use of: (I) primary, secondary or tertiary techniques, (II) natural resources used and (III) environmental compartments affected. Primary sources that address the issue of expanded polystyrene treatment worldwide were consulted. It was found that the best techniques for the recycling of polystyrene are primary and tertiary specifically manual crushing and use of green solvents such as d-limonene and p-cymene, to leave the secondary and tertiary treatments in last positions, agglutination and generation methods of energy respectively.
