Behavior of Concrete Using Marble Waste as A Coarse Aggregate

India has currently taken a major initiative on developing the infrastructure such as express highways,bridges, power projects, international airports, metro rail etc., to meet the requirements of globalization. Inthe construction of buildings and other structures, concrete plays an important and rightful role and a largequantum of concrete is being utilized. Concrete is a reliable material, which is extensively used throughout inbuilding the infrastructure of a nation. India produces more than approximately 170 million cubic meters ofconcrete annually. Investment in construction sector is enormous. Rising cost of construction materials coupledwith the paucity of aggregates is creating problems for the construction industry. On the other hand,disposal and/or utilization of industrial waste is a global issue. One ingenious solution could be to use thewaste material in the production of concrete, if suitable, thereby decreasing the cost of concrete. In India,millions of tons of waste from marble industry is being created after cutting, polishing, processing and grindingof marble. It can be utilized as both coarse & fine aggregate. Using waste generated by the marble quarriesto produce aggregates for producing structural concrete has therefore been studied as a useful alternativefrom the perspective of environmental protection and sustainability of natural resources.The aim of this paper is to study the performance of concrete prepared by using marble waste as coarseaggregates, at elevated temperatures. Since concrete is better known for its compressive strength, its qualitywas checked at high temperatures by using non-destructive tests like the Thermo gravimetric analysis, UVPulse velocity test & visual inspection The main goal of this study is to demonstrate the possibility of usingmarble wastes as a substitute rather than natural aggregates in concrete production. The paper presents thestudy methodology, the characterization of waste marble aggregates and various practical formulations ofconcrete.Keywords: Marble, NDT, BCS
