A Report Comprises of the Consequence of Using Salt Water (Sea Water) Over Normal Water in Concrete Casting

Abstract: In this research work, the effect of saline water on the compressive strength of concrete was investigated. This paper therefore gives a broader view on the result and findings of an experimental research on the effect of salt water on compressive strength of concrete. For this concrete cubes were cast using fresh water and salt water for a design mix of M-30 1:1.7:3.30 by weight of concrete, and 0.45 water- cement ratio. 50% of concrete cubes were cast and cured with fresh water and remaining 50% cubes were cast and cured with salt water. The concrete cubes were cured for 7,14 and 28 days respectively. The result of the average compressive strength of concrete obtained using fresh water ranges from 25.1- 37.3N/mm2 and using salt water ranges from 28.40 – 40.34N/mm2.
