Abstract
The aim of this work is to broadly investigate the possibility of utilizing excavated soil as alternative for river sand in cementitious system. Three different types of soils with low, medium and high plasticity (with different proportion and type of clay) were used as fine aggregates to produce cement mortar. The same soil samples were treated by dry sieving through 600 µm size sieve and/or stabilized with calcium bearing stabilizers viz., lime and slag, to improve the mortar properties. Different dosages of stabilizers (up to 20%) have been tried to stabilize the clay present. Treated plastic soils were then used as fine aggregate in cement mortar. Mortar properties such as strength and shrinkage were determined and compared with control mortar made of river sand. Results showed that it is possible to use low plastic soil as fine aggregate by employing simple dry sieving without compromising mortar properties. Medium plastic soil needs stabilization together with dry sieving to reach an acceptable limit of shrinkage strains. Though mortar with high plastic soil shows improvement in properties, shrinkage strains are not controlled with these treatment methods.
