Abstract-
Stone Crushers are operating in many parts of India to supply coarse aggregates for various types of construction especially for concrete construction. Stone powder is considered a waste product obtained by breaking down larger size stones into smaller sizes for making coarse aggregate. In India Stone powder is produced in large quantity and therefore their consumption becomes necessary in order to keep the surrounding environment clean and pollution free. By utilizing stone powder as replacement of sand would reduce the environmental problems and also results in economical concrete. Normally river sand is used as fine aggregate in concrete. The main function of the fine aggregate is to assist in producing workability, reducing drying shrinkage and uniformity in the mixture. Due to increase in construction, the available sources of natural sand are getting exhausted. Now-a-days the natural river sand has become scarce and very costly due to over exploitation; this factor stimulated the construction industry to go for an alternative material which can serve as fine aggregate. The main aim of this study is to explore the feasibility of utilizing stone powder as an alternative of natural river sand in concrete and assess the effect of stone powder on the properties of concrete in fresh and hardened state. This study has been carried out at 0%, 15%, 30%, 45% and 60% replacement of natural river sand with locally available stone powder. The workability of fresh concrete was checked by carrying out slump cone test. The compressive strength was checked at the age of 7 days and 28 days. Splitting tensile strength and flexural strength was checked at the age of 28 days.
