Rice Husk Ash is used to find the compressive strength of concrete

Abstract

Rice husk ash technology application in concrete has added the efforts to improve its properties by altering the microstructure. Rice husk ash materials, by virtue of their very small particle size can affect the concrete properties. The use of rice husk ash of size 236 nm is study to improve the compressive strength of concrete. By replacing the cement with rice husk ash of 0.3%, 0.6% and 1% b.w.c experimental investigation has been carried out. The test shows a considerable increase in early-age compressive strength and a small increase in the overall compressive strength of concrete. With the increase in the percentage of rice husk ash, the strength increase was observed.
