Abstract

Common river sand is expensive due to excessive cost of transportation from natural sources. Also large-scale depletion of these sources creates serious environmental problems. In such a situation the manufactured sand can be an economical alternative to river sand. Manufactured sand is defined as the residue, tailing or other non-valuable material after the extraction and the processing of rocks to form fine particles less than 4.75 mm (0.19 inch). Use of manufactured sand as fine aggregate in concrete and mortar draws serious attention of researchers and investigators. Durability problems of concrete are associated with the severity of the environment. In this paper, mix design has been developed for M 20, M 30 and M 40 grade concrete using various proportions of manufactured sand and natural sand as fine aggregate incorporating the parameters of particle size and specific gravity. The deteriorating effects of sulfuric acid solution on concrete have been ascertained through the strength reduction tests.
