PEMANFAATAN LIMBAH MARMER DAN SERBUK ZEOLIT SEBAGAI MATERIAL PADA BATA RINGAN CLC (CELLULAR LIGHTWEIGHT CONCRETE)

Abstract

This research is to develop alternative materials derived from natural materials and waste. Waste resulting from the processing industry marble marble and zeolite powders to be used as a material in the manufacture of lightweight brick CLC (Cellular Lightweight Concrete). This research creates innovation of environmentally friendly building materials production and economic value without compromising quality. The research objective was to determine the effect of replacement of sand with marble waste and replacement of Portland Cement (PC) with zeolite powder of compressive strength, water absorption and a specific gravity of lightweight brick CLC. The design of experiments conducted on eight variations of the material composition with the replacement of 20%, 40%, 60% zeolite and 20%, 80% waste of marble. The experimental results show the use of zeolite powder of 20% and 80% of marble waste produces compressive strength of lightweight brick optimal CLC. The use of marble waste and zeolite powders lead to an increase in specific gravity and water absorption of light brick CLC average by 23% and 14%. The composition of the mixture light brick CLC most optimal in terms of compressive strength, specific gravity and water absorption meets the standard for comparison 1 adhesive: 2 aggregate is at 80% PC, 20% zeolite, 20% sand and 80% Waste marble (0.8 PC : 0.2 Zlt: 0.3 Ps: 1.2 PSL).
