“EXPERIMENTAL STUDY ON ENHANCEMENT OF CONCRETE USING MARBLE DUST AS PARTIAL REPLACEMENT OF CEMENT”

According to global cement magazine, each ton of cement produced releases about the same quantity of Co2. During the production of cement energy is consumed and consequently Co2 is emitted to the atmosphere. There is a need to understand the nature of energy utilization in embodied energy in buildings and maintenance, since developing countries like India have limited energy resources vis-a-vis the large population. Leaving the waste materials to the environment directly can cause environmental problem. Hence the reuse of waste material has been emphasized. Waste can be used to produce new products. Green concrete concept of thinking environment into concrete considering every aspect from raw materials manufacture over mixture design ,construction, and service life. Green concrete is very often also cheap to produce ,because for example ,waste products are used as a partial substitute for cement ,charges for the disposal of waste are avoided energy consumption in production is lower ,and durability is greater. The advancement of concrete technology can reduce the consumption of natural resources and energy sources and lessen the burden of pollutants on the environment . To overcome the above, first of all selecting the right material from natural resources and energy sources and lessen the burden of pollutants on the environment in our surrounding area to be thoroughly studied and collected. For this study, we have taken the large amount of “marble dust” generated in natural stone processing plants which have an important impact on the environment and humans around our nearby districts . This study is to investigate the strength of concrete using the “marble dust” as partial replacement of cement. The specimens are casted with marble dust as partial replacement of cement varying from 0% to 25%.The specimens are subjected to cube test , cylinder test, flexural test, pull out test and durability test . The strength and characteristics shall have been studied with the conventional concrete .
