Influence of TerraZyme on Compaction and Consolidation Properties of Expansive Soil

Augmentation as well as stabilization of soils is extensively used as a substitute due to the lacking of appropriate material on site. In this manuscript, universally available bioenzymes (TerraZyme) and their effect on engineering properties of soil are discussed. Differential Free Swell, Consistency Limit, Modified Compaction and Consolidation tests were conceded out in the laboratory for dissimilar mix proportions of TerraZyme with black cotton soil and from the results addition of the TerraZyme to the soil reduces the clay content and increases in the % of coarser particles, reduces Liquid limit values are decreasing and plastic limit increasing irrespective of the percentage of addition of TerraZyme. Maximum dry density increases and OMC goes decreasing with increase in % of TerraZyme. The consolidation parameters compressive index and coefficient of compressibility are decreased. From the above results, TerraZyme can be utilized for intensification of the expansive soil with a substantial save in cost of construction.
