Rice husk ash (RHA) is a natural byproduct obtained from paddy rice during the rice husk processing phase. This husk is characterized by its composition, consisting of approximately 50% cellulose, 30% lignin, and 20% silica. Through a controlled thermal decomposition process, the husk is burned, transforming it into ash that predominantly comprises amorphous silica, ranging between 89-95%. During controlled thermal decomposition, the ash undergoes a transformation, turning into a highly pozzolanic material with an exceptionally large external surface relative to its weight.
