Abstract

In this study, industrial waste in the form of coal ash was used to replace certain percentages of cement in cement-sand bricks production. Two percentages of 15% and 30% of coal ash cement replacement were applied in this study, with the cement-sand ratio and water cement ratio of 1:5 and 0.5, respectively. All specimens were tested for compressive strength at 28 days. The findings show that 15% of coal ash replacement provides the highest compressive strength which able to increase up to 84.6% compared to the control specimens.
