Experimental Study on Replacement of Fine Aggregate by Quarry Waste and Partial Replacement of Cement by Artificial Pozzolans.

Sand is one of the constituents used in the production of concrete. Become expensive and also a scarce materials. In view of this there is a need to identify suitable alternative material waste in place of river sand. The utilization of quarry dust which is a waste material has been accepted as building materials in many countries for the past three decades. Recycling involves processing used materials into new products in order to control the waste of potentially useful materials, reduce the consumption of fresh raw materials. Reduce energy usage, reduce air and water pollution for waste disposal. Concrete traditionally consist of cement, fine aggregate, coarse aggregate and water. The use of pozzolanic materials is as old as that of art of concrete construction. That the suitable pozzolans used in the appropriate amount, modify the certain property of fresh and hardened mortars and concrete. Specimens of concrete made by lime and volcanic ash from mount Vesuvius were used in the construction of Caligula wharf build in the time of Julius Caesar nearly 2000 years ago is now existing if a fairly good condition. A number of structures stand today as evidence of the superiority of pozzolanic cement over lime.
