Soil Stabilization with Rice Husk Ash IntechOpen
Apr 25 2016 · Rice husk ash (RHA) is a by-product of rice milling. Its use as a soil stabilizer is an alternative to the final disposition with environmental benefit. Because RHA is not self-cementitious a hydraulic binder such a lime must be added to form cements to improve the soil strength. Researches on stabilization by applying RHA and lime combinations were conducted in sandy soils.

Most of the evaporable components of rice husk are slowly lost during burning and the primary residues are the silicates. The characteristics of the ash are dependent on (1) composition of the rice husks (2) burning temperature and (3) burning time. Every 100 kg of husks burnt in a boiler for example will yield about 25 kg of RHA.
