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.
