Summary:The soils are an essential component of the foundation and the foundation is an important element of all civil engineering structures. An inadequate mechanical performance of soil is the cause of many premature structural failures. Fly ash is one of the numerous waste substances which contribute environmental pollution, disrupt ecological cycles and set off environmental hazards. Proper and effective disposal of fly ash is a huge task and efforts are underway to improve the use of fly ash in several ways. In the present work, laboratory investigations have been made to study the compressibility behavior of soil and fly ash used in successive layers. The soil and fly ash may be provided in successive layers for getting comparable high strength and low compressibility. Compressibility of the soil decreases due to the silt size particles of the fly ash used. Pre-consolidation pressure of the soil increases with the uses of soil and fly ash in successive layers. Experimental test results show that fly ash may be an effective stabilizing material to reducing the settlement during primary consolidation and secondary consolidation.
