Different mix proportions of sand, cement and rice husk ash (RHA) were studied for use in sandcrete blocks. Optimum water/(cement+RHA) ratios were determined at different mix proportions. Compressive strengths of various mix proportions at 7, 28 and 60 days were also determined. The optimum water/(cement+RHA) ratio increased with rice husk ash contents.

Rice Husk Ash - A Sustainable Material for Concrete

Rice husk needs to be converted into rice husk ash (RHA) for it to be used as a cement alternative or an additive in concrete production. The process requires husks to be burned at a temperature of 600-700 °C for two hours. Careful burning is crucial in order to achieve the right properties for creating good concrete.
