The Potential of Black Rice Husk Ash (BRHA) in Brick Productions

A lot of researchers have studied the rice husk brick and it is the most widely used material in earth construction. Although study has been carried out on rice husk brick previously, more in-depth study on the aspect of the optimal replacement levels of local black rice husk ash to the Ordinary Portland Cement (OPC) that will meet stated standard requirements for non load-bearing bricks need has not been carried out. Despite all the natural materials have been used in construction materials, black rice husk ash is important to be reviewed based on the rationale of availability and growing rice husk production year by year due to high demand of rice supply.
