Durability Characteristics of Sea Sand in Cement Mortar for the Construction

Abstract

AbstractThe utilization of river sand in construction lowers the natural resources when the river sand is dredged from the cross section of the riverbed, which reduces the water table and causes soil erosion. Similarly, the use of manufactured sand is a replacement for the river sand, which is manufactured through the crushing of natural granite stones. The advantage of using manufacturing sand reduces transportation costs and gives good strength and durability characteristics compared to river sand. The production of manufacturing sand causes air pollution, water pollution, which leads to global warming. By referring to the literature, the sea sand can be used as a replacement for river sand. The minimum replacement of sea sand gives the acceptable compressive strength of concrete. In this research paper, we have assessed the physicochemical properties of sea sand, referring to code IS 2386-3 (1963), and compared them with natural sand. The cement mortar using ratio 1:6 is cast by referring to code IS 2250 (1981) with a proportion of 0, 10, 20, 30, 40, and 100% with river sand. The strength and durability characteristics: chlorine test and carbonation test of mortar are determined.KeywordsSea sandPhysiochemical propertiesChlorine testCarbonation test
