INVESTIGATION OF THE IMPACT OF SELECTED ADDITIVES ON INDEX PROPERTIES OF SUBGRADE SOILS
Keywords:

An investigation into the effects of steel slag and saw dust ash on index properties of selected subgrade soils is here presented. The influence of various percentages by weight of steel slag and saw dust ash on index properties i.e. liquid limit, plastic limit, plasticity index and linear shrinkage of subgrade soils were deduced from the results of laboratory analysis conducted in accordance with standards. The results obtained showed that values of the index properties decreased as the quantities of steel slag and saw dust ash added to the soils increased and vice versa.
