Abstract: Concrete is a mixture of a cement, fine aggregate and coarse aggregates with water. Now a day the availability of natural aggregates is less and it is getting depleted. Even though it is available it is too costly to use it in the construction field. Hence we are thinking the alternatives to the natural aggregates. In India the extractive activity of decorative sedimentary carbonate rocks, commercially indicated as marbles and granites, is the most thriving industry. Due to the new emerging innovative ideas in construction field People are owing to renovate their buildings and also demolishing the old ones to reconstruct the buildings. Due to the demolition of buildings, the demolished waste is generated and it’s a big challenge to dispose it off. So we are trying to solve this problem in the view of protecting environment by utilizing this waste by replacing the natural coarse aggregates with this waste. Our main objective is to know the behavior of concrete with replacement of fine aggregate with marble powder and coarse aggregate with demolished waste respectively. The main parameter is to study basic engineering properties of the cement aggregates and compressive strength Also to establish the effect of marble powder and demolished waste and marble dust on the properties concrete mixes. To study the effect of varying percentage of demolition waste as a replacement to natural aggregates on the performance. The collected construction and demolition waste were crushed, sieved and according to gradation it was separated with a required quantity for the analysis. Natural aggregates according to gradation with the percentages of 0%, 10%, 20%, 30% replacement was used, and casted molds.
