PEMANFAATAN ABU DASAR (BOTTOM ASH) DAN KAPUR SEBAGAI PENGGANTI SEBAGIAN SEMEN PADA PAVING BLOCK SESUAI DENGAN SNI 03-0691-1996
Abstract
The purpose of this research is to utilize bottom ash and lime as substitute partial cement to know quality of product based on SNI 03-0691-1996, so that can reduce unused B3 waste. This research used an experimental method, the population of paving block using bottom ash and lime as substitute partial of cement within 5 percentage 25%, 30%, 35%, 40%, and 45% of the amount of cement used in the normal mix. This research examined the six test, namely: compressive test, wear resistance, resistance to sodium sulfate, water absorption and testing measure. The result showed that the difference of quality of product which have different percentage.Percentage 25% and 30% showed B quality based on SNI 03-0691-1996. Percentage 35% showed C quality and 40% showed a D quality based on SNI 03-0691-1996. Percentage 45% showed result below quality based on SNI 03-0691-1996. The optimum paving block produced is 30% which has average 20,66 MPa result on compressive test and maximum 21,86 MPa, 0,086 mm/minute maximum for wear resistance from 35% percentage and 2,25% is maximum amount for water absorption test from 30% percentage. In this research all product which used bottom ash and lime has average 0.744% resistance of sodium sulfate.
