Thermal and Mechanical Properties of Cement-Eps-Marble Powder Composites

Abstract

This work was undertaken to produce a new construction materials which could have insulation and mechanical strength properties by using two different wasted materials. The waste expanded polystyrene (EPS) and marble powder were used as the aggregate in order to produce a new concrete material. After waste EPS is collected as packaging material, it is mixed with the cement of percentages; 20%, 40%, 60% and 80%. Marble powder is added to each of this cement at 0.0%, 0.5%, 1% and 1.5% of the weight of the mixture. 16 different samples were produced. At the end of 28 days of drying period, the samples were subjected to a number of tests so that their physical characteristics could be identified. As a result of these test, it was concluded that EPS ratio of the samples increased, their density, thermal conductivity, the compression and tensile strength decreased, while porosity increased. It was recommended that; using EPS aggregated and marble powder added concrete, (i) the waste EPS and marble powder can be evaluated as construction material, (ii) building heating and cooling energy will be saved.
