| dc.description.abstract | Styrofoam waste is a type of inorganic waste that takes a very long time
to decompose, thus emphasizing the need for utilization efforts. This
research aims to determine the effect of substituting styrofoam on the
volume of sand and to find the optimum substitution of styrofoam in the
concrete block mixture. The composition of the concrete block mixture is
1 cement: 7 sand, with variations of styrofoam replacement at 0%, 10%,
15%, 20%, and 25% of the sand volume. Standard testing according to
SNI 03-0349-1989 is used to measure compressive strength and water
absorption, in addition to volume weight and heat insulation tests for the
concrete blocks. The results of this research show that the use of
styrofoam in concrete block production can produce lighter blocks, with
efficiency in heat insulation, and greater resistance to water. Although
the compressive strength of the blocks decreases, the environmental
benefits derived from recycling styrofoam waste can be a crucial
consideration in the development of sustainable construction materials.
In this study, an optimum substitution of 15% styrofoam for the sand
volume was also determined. | en_US |
