Industrial Wastes in Soil Improvement

الملخص EN

Soil existing at a particular site may not be appropriate for construction of engineering structures.

The present study made an attempt to enhance the geotechnical properties of a soil replaced with industrial wastes having pozzolanic value like rice husk ash (RHA) and fly ash (FA).

Soil is replaced with RHA in 2%, 4%, and 6% to dry weight of soil.

It is observed that soil replaced with 4% RHA is the optimum for the soil used in this study from geotechnical point of view.

To know the influence of fly ash, soil is further replaced with 4% FA along with 4% RHA.

It is found that results of soil replacement by both RHA and FA proved to be soil modification and not the improvement.

Hence, a cost-effective accelerator like lime is used for further replacing the above soil-4%, RHA-4% FA mix.

The optimum lime content is found to be 4%.
