Abstract
To enrich the performance of structures, the stability of underlying soils must be checked. The stability of soil may change due to discharge of pollutants into water bodies without adequate treatment which causes momentous changes in the behaviour of water and further leads to changes in the pH of water. In the present study the black cotton soil has been treated with ordinary Portland cement of 53-grade and Portland slag cement with different percentages (3, 6 and 9%), and laboratory tests such as Atterberg limits, compaction, UCS, CBR and consolidation have been performed. This paper attempts to assess the effect of pH (pH = 5, 7 and 9) levels on curing time (7, 14 and 28 days) behaviour of cement-treated soil. Test results have shown that there is an increase in OMC which leads to decrease in MDD. The UCS and CBR strengths of soil got increased due to the addition of cement; besides that, there is a reduction in the compressibility with the addition of cement content which were cured for ages (7, 14 and 28 days).
