What is Rice Husk Ash in Concrete Mixes about?

This document summarizes a study on replacing cement in concrete with rice husk ash (RHA). Rice husk ash is a byproduct of the rice milling process that contains 85-90% amorphous silica. The study investigated partially replacing cement at 0% and 20% replacement levels with RHA. Testing showed that concrete with 20% RHA replacement exhibited higher compressive strengths at 14, 21, and 28 days compared to the 0% replacement concrete. Thus, partially replacing cement with rice husk ash can improve the propert
