The Possibility of Produce Self Compacted Polystyrene Concrete

Abstract

The aim of this study is to produce one types of self-compacted lightweight concrete which is known as self-compacted polystyrene concrete (SC-PC) . The SC-PC was produced by using expanded polystyrene beads as a partial replacement by volume of sand,(Glenium 51) as a superplastisizer and styrene butadiene rubber (SBR) as a viscosity modifying agent to prevent the segregation of beads .Also studying the fresh and hardened properties of (SC-PC) (density, compressive, strength, flexural strength and tensile strength). The results indicated that it is possible to use polystyrene beads for producing (SC-PC) with density ranging from (1660-1895)kg/m3 and a 28-days compressive strength ranging from (10.23 – 14.65)MPa .The results also showed that the properties of (SC-PC) are mainly influenced by the content of polystyrene beads and decrease with the increase of polystyrene content . The density of (SC-PC) decreases to (12.4%) when the percentage of sand replacement with polystyrene beads increased from (16.7% to 50%) .While the compressive ,
