A Development Compressive Strength of Concrete Mixed With rice husk ash By Crushed Dust Replace Sandand Effective Microorganisms

Abstract

This research aims to study the concrete mix with crushed dust and rice husk ash . Purpose to improve the compressive strength of mortar using by palm ash replaced cement 0, 10, 20, 30, and crushed dust replaced sand 100, 90, 80, 70 percent by weight curing 1, 3, 7, 21 and 28 days compressive strength test results showed that the mortar. Mortar mixed with crush dust and rice husk ash is expected to be better than the compressive strength of standard mortar. The compressive strength of mortar will be reduced palm ash. By the highest compressive strength at 28 days is 497.42 kg / cm while the compressive strength of mortar control are 199.76 kg / cm. rice husk ash and crushed dust in the right amount. Will assist in the development of the compressive strength of mortar in short and long term.
