Use of rice husk in cement production

Over the past decade, concrete technology has expanded for multiple applications with the introduction of high strength and ultra high strength concrete. However, challenges exist with substantial heat liberation during the process which leads to cracking. Use of minerals compounded with high strength concrete are found to minimize the quantity of cement needed, while also providing the same properties. This minimizes the heat liberated and in turn cracking. 

One of the potential natural minerals is rice husk which is a by- product taken from rice mill process, with approximately the ratio of 200 kg per one ton of rice, even in high temperature it reduces to 40 kg.

Use of rice husk ash as a pozzolanic reactive material helps to improve the surface area of the transition zone between the microscopic structure of cement paste and aggregate in the high-performance concrete.
