Shell charcoal ash and rice husk ash are industrial by-products which have the potential to replace sand for concrete mix, especially in Indragiri Hilir. The research with the title "Effect of Mixture of Rice Husk Ash and Shell Ash Ashes as Substitute for Some Fine Aggregates Against Concrete Compressive Strength" aims to prove the effect of a mixture of shell charcoal ash and husk ash to replace some of the sand to produce maximum compressive strength. Concrete is a mixture of Portland cement, fine aggregate, coarse aggregate, and water. This research uses 5 variations of the mixture to the weight of sand, BSA 0 without a substitute mixture, BSA 1 with a mixture of 5% husk ash and 10% shell charcoal, BSA 2 with a mixture of 5% husk ash and 15% charcoal ash, BSA 3 with a mixture of 5% husk ash and 18% charcoal, BSA 4 with a mixture of ...
