Feasibility Analysis of Marble and Granite Waste as Partial Replacement of Natural Sand in Mortar Mix

Jasveer Nagar, Mahendra Saini

Abstract: In this study an investigative experiment is reported on mechanical properties of mortar modified by marble and granite dust as replacement of fine aggregate or naturals and. An endeavor has been made to evaluate the compatibility of marble and granite dust as construction material. Properties of mortar are investigated for 1:4 mix proportions. Marble and granite waste is individually replaced till 50% at interval of 10% by natural sand. Water demand is examined for individual mixes and compared to control samples. To ensure the quality of various mixes compression, flexural strength and drying shrinkage is measured. Volume of voids and water absorption capacity are compared to ensure the durability of mortar mixes. Overall, it can be concluded from above observation that optimum 30% for marble and 20% for granite waste can be utilized individually in mortar mixes.
