Feasibility of using Rice Husk Ash as Partial Replacement for Concrete

This study examined the feasibility of using rice husk ash as partial replacement for concrete. Concrete cubes tested comprise the Control and Specimen. The percentage of replacement in the specimen cubes varied from 5 to 20 in a mix of 1:2:4. Various tests considered and the results showed that rice husk ash replacement has better performance on the compressive strength of the concrete when the added percentage is not more than 10%, while observation showed that the application of rice husk ash has a reduced density when compared with the
