Pengaruh Limbah Bahan Bakar Batu–Bara ( Bottom Ash ) sebagai Bahan Tambah Agregat Halus pada Campuran Beton

Abstract

Concrete is a function of its constituent ingredients comprising hydraulic cement, coarse aggregate, fine aggregate, water and the added material.The use of coal as an energy source produces a residue in the form of bottom ash that cause environmental pollution. The use of bottom ash as fine aggregate added material is one way to resolve the issue. This study aimed to examine the effects of the use of bottom ash as a fine aggregate added to the concrete mix.This research was conducted by examining the effects of the use of bottom ash as fine aggregate added material by 50% and 100%. Thus from this study found that the best percentage of fine aggregate added smalller levels of bottom ash, the higher the compressive strength values
