Abstract: Most
of the soil in their natural condition lack the
strength, dimensional stability and durability required
for building construction. In the present investigation
an attempt is made to study and improve the quality of
locally available red lateritic soil by stabilisation.
The granite cutting and polishing dust obtained from
granite tile industry and lime are used as stabilisers.
The granite dust is dumped as a waste material usually
in rivers, lakes and landfills resulting in
environmental problems. The use of stabilised blocks
involves no pollution and is cost-effective, thus
further benefiting the environment by saving
deforestation for burning fired clay bricks. The study
focuses on correlating the Unconfined Compressive
Strength (UCS), Optimum Moisture Content (OMC) and
Maximum Dry Density (MDD) by stabilising locally
available lateritic soil with granite dust and adding
lime up to 15% by dry weight of soil. The investigation
revealed an improvement in compaction characteristics.
The UCS value after 7 days and 28 days of curing shows
increasing trend up to 9% addition of lime and
thereafter shows a decreasing trend. Hence 9% lime
addition is found to be the optimum value for getting
maximum strength and durability. The 28 days average
compressive strength of the blocks casted using the same
mix gave a better strength than the conventional bricks.
