Abstract:
There is a deficiency of row materials for
housing in Sri Lanka because of population growth. So
there is an unfulfilled demand for traditional row
materials such as river sand and clay. Serious
environmental problems are caused because of over
excavation of above row materials. To minimize the
environmental problems, it should be focused towards
low cost and environmental friendly alternative row
materials which are occurring in sufficient amount in
Sri Lanka. In order to fulfill the demand of row
material for housing and other constructions, laterite
soil can be used with quarry dust and cement as
additives. Particle size distribution of the laterite was
poorly graded and addition of quarry dust corrected
this deficiency. The bricks which are made from laterite
and quarry dust mixture can be stabilized using low
amount of cement while achieving required
compressive strength for walling. This material mixture
is more economical and environmental friendly for
bricks production.
