Abstract

River sand is available naturally and are immensely utilized in construction industry. It is relatively clean, coarse, chemically inert and needs very less or no treatment before being put into use. The use of fresh water poses a significant difficulty in many regions of the world due to drought and the obtaining of river sand as fine aggregate has detrimental effects on river ecological system. To find an alternative for river sand and fresh water is an absolute necessity. The majority of investigations have discovered SWSSC to have equivalent properties as conventional concrete. This thesis performs an experimental study on the 28 and 90 days strength and durability parameters of conventional and SWSSC. Also different percentages of Ground granulated blast furnace slag are added for the SWSSC for finding the variation of strength and durability parameters. An optimum percentage of GGBS added to seawater sea sand concrete was obtained. Load- deflection study on SWSSC beam reinforced with steel as well as SWSSC BRFP beam was conducted.
