Experimental Investigation on Self Compaction Concrete by Partial Replacement of Cement with Ground Nut Ash and Fly Ash

Self-Compaction Concrete is a mixture of cement, fine aggregate and coarse aggregate, which is mainly derived from natural resources along with addition of superplasticizers to increase the flowability of concrete. Increasing population, expanding urbanization, climbing way of life due to technological innovations has demanded a huge amount of natural resources in the construction industry, which has resulted in scarcity of resources. India is facing a serious challenge in disposing the waste in landfills throughout the country. The landfill disposal is resulting in high disposal costs and potential environmental problems. If current trend continues, waste production will grow by 5% each year, which will ultimately result in saturated capacity of landfills by 2020. This project reports on the results of an investigation of utilization of ground nut ash as additional material in concrete mixes to be used for housing projects, for which it must be assured that the resulting concrete has the proper strength, beyond to the addition of Ground nut ash fly ash was also considered as 10% for all mixes. Concrete mixes containing various contents of the Ground nut ash and fly ash were prepared and basic characteristics such as Flowability tests, compressive strength, and split tensile strength were determined. Four concrete mixes with 0%, 10%, 20%, 30% and 40% of ground nut ash and fly ash as an additional material to the concrete were prepared for M-30 concrete.
