Abstract

This study has an objective to assess the utilization of grains epoxy polystyrene, or better known as Styrofoam that have light density, to serve as a partial substitution of sand in concrete materials . On the use of 5% EPS concrete compressive strength characteristics obtained amounted to 18.69 MPa (down approximately 20.9% of the normal mixture). While the use of 10% EPS, decrease concrete compressive strength of 21.67% ie 18.51MPa. Modulus of elasticity of concrete decrease with the addition of the percentage of EPS, the use of EPS up to 40% decrease modulus of elasticity to be 16.219 MPa (down around 21%). The relationship between the modulus of elasticity (E), Specific Gravity (wc), compressive strength (f/c) and the percentage of EPS (p) can be expressed in an empirical equation as follows :E= (wc)1,50,05exp(−0,23p)√f/c.
