Mining Sand And Sea Sand As Fine Aggregate 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.
