Effect of different district water sources on compressive strength on concrete

Abstract

The quality of mixing water may affect the setting, hardening and strength of the concrete. Concrete is the most durable material and cement provides the large amount of energy to structural materials in concrete. Here the principal consideration is to mixing the quality and quantity of water into the concrete preparation. For the preparation of concrete quality of water always plays a major role. Quality of water may vary according to places; hence it may change the behaviour of concrete. It is seen that the water may affect strength, workability, setting time, compressive strength. According to IS3025 (Part II):1983, pH value of water should be potable between the range of 6.0 to 8.0 pH, it is favourable for construction work. The works aim is to provide a new approach of concrete compressive strength and also check the alkalinity, total suspended solids, sulphate, hardness etc. Samples are collected by different district (Durg, Rajnandgaon, Kawardha, and Balod) of Chhattisgarh. Here we get different types of Minerals in every district. So this is done to determine the Compressive Strength Test of Concrete by making concrete cubes. The samples of concrete (cube) were made for two different Grade i.e. mix design of M20 and M25 and with variable water cement ratio. The result after tests were compared and determination of various aspect of water were made if they are suitable to use for structural member of building and related structures Keywords- Compressive Strength, Setting time, Water test, Impurity, pH value, Strength, Sieve analysis, W/C ratio, PPC cement, Workability test, Structural member
