Experimental Investigation on Partially Replacement of Fine Aggregate with Kota Marble Dust and Coarse Aggregate with Tyre Rubber Tube Fiber

Abstract

As construction in India and other developing countries increases, the consumption of energy and resources is also increasing in an alarming way. Most of the developing nations have reduced the usage of virgin material like aggregates in construction, due to economic and environmental reasons, so they focused on the environment, safeguarding of natural resources, and recycling of wastes materials. Many industries produce lot of waste products, which is disposed into landfills. This material can be reused in construction industry as alternative to conventional materials. Such practice conserves natural resources and reduces the space required for the landfill disposal of these waste materials. In this investigation, Mix M40 is to be designed first to evaluate the strength of cement concrete mix using two waste products namely rubber fibers and kota stone marble. Rubber fiber is partially replaced with coarse aggregates and kota stone marble is partially replaced with fine aggregate. The dimensions of the rubber fibers taken as 50-60 mm in length and 1.5 - 2 mm in width. The concrete mix was treated with rubber fibers and kota stone marble in various mix proportions. Then various tests were conducted to determine the different concrete properties such as compressive strength and split tensile strength on the samples of concrete. The compressive strength test and split tensile strength test were performed on the cubes and cylinders respectively with the partial replacement of coarse aggregates at 5%, 10%, 15% and 20% by weight with the rubber fibers and 0%, 7%, 11% and 15% kota marble stone with the fine aggregate. The major advantages of using an industrial waste i.e. kota stone marble is in the construction of roads and to reduce the problem of disposal of these wastes which as a result helps to reduce the chronic diseases caused by it. The use of rubber fibers improves the properties of concrete like elastic behavior, insulation against heat and sound.
