Effect Of Curing Water Quality On Mechanical Strength Of Concrete

Abstract

The quality of the ingredients used in the production of concrete determines its strength. Mixing and curing water is one of the components required, and it should be suitable for producing concrete. Impurities in water can reduce concrete strength and induce corrosion of reinforcement, hence water quality is critical. In developing countries such as Bangladesh, the usage of fresh water is increasing, which can result in a decrease in freshwater availability. As a result, other sources of water were utilized as a substitute for concrete mixing and curing. This study examined the effects of various water sources on the mixing and curing of concrete. In this study, water samples were collected from different water sources (river water, sea water, effluent treatment plant and Fresh water), and their chemical properties were conducted based on standard laboratory procedures to identify the constituents. Experimental tests were conducted on workability of concrete and compressive strength of concrete. The results obtained from the compressive strength test of concrete cylinder cast at the curing ages of 28 days using river water, sea water, effluent treatment plant and fresh water. Compressive strength testing of cylinder using fresh water for mixing and other sources of water used for concrete curing only. River water shows improved performance for concrete curing, and it can be properly utilized for concrete production
