Experimental Investigation on Properties of Concrete by Using Different Types of Water

The impact of several types of mixing water on the compressive, flexural, and tensile strength of concrete was explored in this study. The research focused on the impact of varied water quality on concrete compressive strength. The investigation focused on a concrete mix of M30 grade with a water cement ratio of 0.4. Water samples were obtained from several sources on campus, including bore well water, waste water, well water, sea water, and mineral water (packed drinking water), and utilised to cast 150mm×150mm×150mm concrete cubes and 150mm×150mm×750mm concrete beams. The cured cubes and beam were crushed after 7 and 28 days to determine compressive, flexural, and tensile strength The results revealed that the compressive strength of concrete cubes formed using mineral water, tap water, well water, and waste water increased with time and had little fluctuation. The effects of other contaminants, such as silt and suspended particles, on concrete strength were also looked at. Chemical analysis was performed on water samples from five different sources to determine their chemical composition. These water samples were used to make 150mm cube samples. The cubes were put through a compressive strength test, and the results were analysed statistically. The findings revealed that the kind of water used in concrete mixing had a considerable influence on the final concrete's compressive, flexural, and tensile strength. It ended by recommending that if tap water is inadequate, river water may be utilised for mixing. Other attributes like durability and shrinkage, on the other hand, should be addressed before usage.
