المستخلص: This paper is devoted to study the properties of light weight concrete manufactured from polystyrene, cement, sand and water and that has good strength and thermal insulation and low density compared to other types of light weight concrete which is used as a concrete fill (blinding) or used for non structural concrete members. Seventy two (72) concrete mixs were produced for this study, the three variables are the ratio of cement to sand, the water to cement and the ratio of polystyrene to cement, this is done by changing one of these variables and fixing the other two, these three are cement: sand (C: S = 1:1.5, 1:2, 1:3), water: cement (W/C = 0.30, 0.40, 0.45) and Polystyrene to cement ratio (P/C = 0%, 2%, 3%, 4%, 5%, 6%) The test results of the concrete cubes (288 cubes) shows that the compressive strength ranged between 0.33-6.53 MPa while the density ranged between 775-2118 kg/m3, From these results a mathematical relation was established for easy finding the compressive strength and the density of lightweight concrete, this relation can be used in terms of these variables for any percentage and without any concrete testing.
