Experimental Study on Properties of Granite Concrete

Abstract

Concrete made with Portland cement is probably the widely used binding material in the world. Manufacturing of cement production is one of the concerns worldwide that impact the environment with major impact being global warming due to CO2 emission during the production of cement. Alternatively, when industrial wastes are recycled or reused, CO2 emissions are reduced and less material is dumped as landfill and more natural resources are saved. Hence, this is an attempt to replace the cement by granite powder in concrete. In this experimental study, granite powder was used in concrete as a cementetious material as partial replacement of cement. Replacement of cement by granite powder was made by 5%, 10%, 15%, 20% by weight of cement. For each replacement strength parameter test was conducted. Compressive strength after 7 and 28 days curing was obtained. From the test results it was found that concrete at the level of 15% partial replacement of cement with granite powder has better workability and high compressive strength of 7 days and 28 days curing. The granite dust powder is free of cost. Hence it seems to be economical.
