STUDI PENGGUNAAN LIMBAH SERBUK KACA SEBAGAI BAHAN SUBSTITUSI SEMEN PADA PEMBUATAN BATA BETON PEJAL

Abstract

Waste glass is often the trash unused and potentially damaging to the environment because it is difficult
to decompose. Though glass waste has the potential to be used, one of them as a substitute for cement in
concrete solid brick. The purpose of this study was to determine how much influence the addition of glass
powder waste of compressive strength of concrete solid brick. Manufacture of solid concrete brick made from
waste fine aggregate, cement PC type I, and glass powder from waste glass bottles. Test object of research is
made with a composition ratio of cement, fine aggregate and water with glass powder 4 substitution treatment
were 0%, 10%, 20%, and 30% by weight of cement. Compressive strength testing is done on day 7,14, 21 and
28. From the test results obtained optimum compressive strength value contained in glass powder ratio
variation of 10% of the cement with the compressive strength obtained at 73.33 Kg / cm2 and included into
the Tertiary quality II. This shows the glass powder can be used as an additive in the manufacture of solid
concrete brick so that it can be used as an alternative to environmentally friendly construction materials.
