dc.description.abstractTHE USE OF RICE HUSK ASH AS A STABILIZING AGENT FOR LATERITIC SOILS IN THE MANUFACTURE OF BLOCKS FOR LOW COST HOUSING BY ABDUL-RASHEED ALIMI B.Eng(Civil), GMNSE. A Thesis submitted to the Postgraduate School in Partial fulfillment of the requirements for the Degree of Master of Science, (CIVIL ENGINEERING CONSTRUCTION MATERIALS) in DEPARTMENT OF CIVIL ENGINEERING FACULTY OF ENGINEERING AHMADU BELLO UNIVERSITY, ZARIA, NIGERIA NOVEMBER, 1989 ABSTRACT This thesis describes an investigation of the use of rice husk ash, in combination with cement and lime, as a stabilizing agent for lateritic soils in the manufacture of blocks for low cost housing. The effect of the rice husk ash on cement and lime stabilized soils were studied. In order to improve the strength and effect of moisture on the early strength of lime and rice husk ash cementitious mix (RHA cement), small amounts of cement were added to the mix anu three optimum mixes-were used for the manufacture of blocks. Evaluation of the masonry units indicated that rice husk could constitute up to 60% of the total stabilizer content in soil stabilization, and the mixes are found to be potentially suitable for the production of blocks for low cost housing.
