Abstract - Concrete has become a basic need for every
coarse aggregate by waste construction material reduces the construction of fresh raw materials.
structure now-a-days. The concrete construction plays a vital role in our daily lives and the society in general. The objective of this study is to derive the alternative sources for coarse aggregate in concrete. In this study, we utilized the different kinds of eco-friendly as well as cheaply available waste broken materials from brick, cudappah and marble wastes were investigated for the replacement as well as sustainable of coarse aggregate in conventional concrete process. The mechanical properties of collected aggregates was assessed. All the investigation was conducted on M20 grade using IS design concept. The control specimens such as cubes, cylinders and prisms were cast to assess the performance of concrete for different coarse aggregates. The compressive strength, split tensile test and flexural strength were conducted after 28 days curing. Suitable conclusions were drawn based on the experimental results

Concrete is the widely used construction material for various types of structures. It is one of the most important contemporary civil engineering materials. It is a composite construction material formed by mixing an aggregate with cement and water, then allowing the mixture to dry and harden [Farid Debieb and Said Kenai 2005]. Approximately 60-80% of concrete is made up of aggregates. The cost of concrete and its properties are directly related to the aggregates used. In aggregates the major portion is of coarse aggregates i.e. stone or gravel which are obtained naturally either from river bed or by crushing rocks mechanically up to the required size.

1.3 REPLACEMENT FOR COARSE AGGREGATE The possibility of using substitute for coarse aggregate in concrete serves as one of the possible solutions to the escalating solid waste problem. The disposal of solid wastes in the production of concrete has concentrated mostly on aggregates since they provide the only real potential for using large quantities of waste materials.
In India construction waste production is 165-175 million tons per year [Zainab Z. Ismail 2007]. However brick, marble and cudappah waste are high resistant to biological, chemical and physical degradation forces.
The following construction wastes replacement for coarse aggregates,
This project investigates the feasibility of brick waste, marble waste and cudappah waste as partial replacement with coarse aggregate in cement concrete. These wastes falls in the category of construction waste. Replacement of
