Mechanical Properties of Compressed Stabilised Earth Blocks with Rice Husk Ash

The purpose of this study was to see if Rice Husk Ash (RHA) could be used as a partial replacement for cement in clay soil incompressed earth blocks. The percentage of rice husk ash ranged from 0 to 2.5 percent, 5 percent, 7.5 percent, 10 percent, and 12.5 percent. The blocks admixed with 10% rice husk ash had the highest compressive strength of 1.90 MPa. Water absorption increased continuously as the proportion of rice husk ash increased, with a value of 8.55 percent for the block with 12.5 percent RHA. As the percentage of rice husk ash in the blocks increased, the unit weight of the blocks fell.
