Effect of Water Content on Mechanical Properties of Concrete, Partial and Fully Replaced with Manufactured Sand as Fine Aggregate

As we realize that the development in construction has been improved through the advances in innovation and furthermore in the procedure angles. Concrete, which is the vital part in developing construction industry, is being utilized more than some other man-made material on the planet and it expends more crude material than some other item. The sand type affects the properties of Concrete blend. In this investigation I have supplanted certain level of natural river sand in concrete with manufactured sand and considered its impact on quality in contrast with typical cement on varying water content. Here the river sand is supplanted with half and 30% manufactured sand individually. Additionally the impact of incomplete substitution of river sand by manufactured sand with various water content- 110 liters, 120 liters, 130 liters with fixed binding material of 300kg on the different hardened Concrete tests were led. Compressive strength test is performed and its connection with ordinary concrete was examined. There were 12 proportions of mixes for 7 and 28 days and 6 proportions of mixes of normal concrete for correlation. The objective was to accomplish high quality & high strength concrete by supplanting with manufactured sand with low water cement ratio of 0.36, 0.4 and 0.43 by utilizing super plasticizers. This undertaking with the utilization of manufactured sand in the Construction Industry, manufactured sand will be used to full extent as alternative, decrease the effects on condition by not utilizing the river sand.
