Abstract

Usage of sea sand for concrete development is the possible alternative for river sand and avoids the excessive sand mining which may cause ecological and environmental problems. Sea sand is not used in concrete, since it contains chloride ions which can corrode steel. In order to avoid the corrosion, the salt content of the sea sand must be eliminated before being utilized in concrete. Present paper investigates adopting sea sand as fine aggregate in concrete. The physical properties like specific gravity, percentage of fineness and solubility were carried out in raw sea sand and treated sea sand. The results of the study reveal that the chloride level of treated sea sand is below the acceptable level of 0.075 % weight of sand. The chemical properties of sea sand were also studied by chloride ion estimation.
