Abstract

Background/Objectives: In this study, the construction industries expect a serious shortage of sand in the near future due to over exploitation of river sand. This paper deals with the use of sea sand as substitute for conventional river sand. Methods/Statistical Analysis: M20 concrete mix was designed with sea sand as fine aggregate and the workability, strength in compression and split tension and water absorption characteristics are determined and compared with conventional concrete. Findings: The sea sand, as available, is inferior to conventional river sand but proper washing for two times make it feasible for making concrete. For M20 grade concrete, two times washed sea sand can be used as fine aggregate totally replacing river sand as the workability and strength characteristics reach within the limits of acceptable level. Sea sand utilization is cost effective in coastal line construction. Keywords: Alternative to River Sand,Sea Sand, Sea Sand Concrete, Strength
