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.
