AN EXPERIMENTAL STUDY ON PROPERTIES OF THE CONCRETE FOR REPLACEMENT OF SAND BY STONE WASTE FOR DIFFERENT TYPES OF CEMENT WITH CHEMICAL ADMIXTURE

The demand of natural sand in the construction industry has consequently increased resulting in the reduction of sources and an increase in pric e. In such a situation stone dust can be an economical alternative to the river sand. The effect of water cement ratio on fresh and hardened properties of concrete with fully replacement of natural sand by stone dust was investigated. Concrete mix design of M 40 grade was done according to Indian standard code ( IS: 10262).The main objective of the present investigation is two cements are selected Ordinary Portland Cement (OPC) & Portland Pozzolana Cement (PPC) - 43 grade to evaluate the possibilities of using stone dust as a replacement by fine aggregate along with super plasticizers at a dosage of 0.5%, 1.0%, 1.5% & 2.0% by weight of cement.
