Abstract

Expansive soil causes serious problems on civil engineering structures due to its tendency of swelling when
it is in contact with water and shrinks when it is dry out .The evaluation involves the determination of the
swelling potential of expansive soil in its natural state as well as in varying proportions of marble dust and
solid waste (from 0% to 30%). Addition of marble waste and dust decreases liquid limit, plastic index and
shrinkage index, increase plastic limit and shrinkage limit. Also experimental result shows that swelling
percentage decreases and rate of swell increases with increase percentage of marble dust in expensive soil.
The environmental degradation due to marble mining is much less than the environmental degradation
caused by the waste from marble processing plants.
