Rice husk is an agricultural residue which accounts for 20% of the 649.7 million tons of rice produced annually worldwide1. The produced partially burnt husk from the milling plants when used as a fuel also contributes to pollution and efforts are being made to overcome this environmental issue by utilizing this material as a supplementary cementing material2. The chemical composition of rice husk is found to vary from one sample to another due to the differences in the type of paddy, crop year, climate and geographical conditions3.

Burning the husk under controlled temperature below 800 °C can produce ash with silica mainly in amorphous form3-5. Recently, Nair et al.6 reported an investigation on the pozzolanic activity of RHA by using various techniques in order to verify the effect of incineration temperature and burning duration. He stated that the samples burnt at 500 or 700 °C and burned for more than 12 hours produced ashes with high reactivity with no significant amount of crystalline material. The short burning durations (15 - 360 minutes) resulted in high carbon content for the produced RHA even with high incinerating temperatures of 500 to 700 °C. A state-of-the-art report on rice husk ash (RHA) was published by Mehta7 in 1992, and contains a review of physical and chemical properties of RHA, the effect of incineration conditions on the pozzolanic characteristics of the ash, and a summary of the research findings from several countries on the use of RHA as a supplementary cementing pozzolanic material.

According to the author's literature, RHA has not been utilized in the construction industry yet, the reason for that may be due to the lack of understanding of the RHA blended concrete characteristics.
