Use of Granite Waste for the Application as Coarse Aggregate in Concrete

The granite waste GW generated during mining extraction is responsible for environmental degradation. Millions of tonnes of stored granite waste are currently still not being reused. This paper describes a disposal process for this material, where granite waste can be used as an alternative aggregate for ordinary concrete. The awareness of the impact of coarse aggregate morphology on the behaviour of fresh concrete mixture, as well as on the deformation and compressive strength of the hardened concrete, favours the creation of the efficiency of Concrete. In this project, experimental work will be done on the effect of granite waste on compressive strength of concrete and split tensile strength of concrete with partial replacement of coarse aggregates by 20 , 40 , 60 , 80 , and 100 for 28 days of water curing for M25 grade of concrete. This project concluded that the performance concrete made with waste granite as coarse aggregate subjected to water curing is conducted for finding the characteristic mechanical properties such as compressive strength and split tensile of concrete mixtures at 7, 14, and 28 days of curing for 0.45 water cement ratio. The test results show clearly that waste granite as a partial coarse aggregate has beneficial effects of the mechanical properties of concrete. Of all the 6 mixtures considered, concrete with 20 of granite powder GW 20 was found to be superior to other mixtures for all operating conditions. On the other hand, the tensile strength of the concrete reduced with the increment of granite waste. The effect was more significant in the strength of concrete. The study reveals that when waste granite is added in concrete partially replaced with coarse aggregates, the properties of concrete are satisfactory up to 20 of granite waste. But when percentage of granite waste is increases, the compressive strength and split tensile strength of concrete is decreases. The effect of using granite powder in concrete by partially reducing quantities of coarse aggregates reduces cost of concrete work. Prof. K. A. Salunke | Sumit M. Pardeshi | Prathm N. Patil | Yash A.
