Abstract In this experiment the studies, the strength characteristics of M30 grade concrete are using manufactured plastic coarse aggregate as a replacement of natural coarse aggregate is conducted along with the use of quarry dust as a partial replacement of conventional natural river sand. Mix design for plastic coarse aggregate concrete is done by calculating the specific gravity of the manufactured plastic aggregate, fly ash and quarry dust. Cubes, beams and cylinders were casted by fly ash is 20% in cement, partial replacement of quarry dust in sand and natural coarse aggregate by 5%, 10%, 15%, and 20% of manufactured plastic coarse aggregate. The experimental studies give the final strength parameters such as compressive strength, flexural strength and split tensile strength of the casted cubes, beams and cylinders were tested respectively. Keywords- Quarry Dust, Fly Ash, Plastic Coarse Aggregate

I. INTRODUCTION A. General Concrete is a constitute made essentially of Portland cement, fine aggregates, coarse aggregates and water. The mixture of the materials will undergo in a chemical reaction called hydration and this process will result in a change of mixture from plastic state to a solid occurs over a period of time. By reducing the weight and cost of constituent's materials in concrete, the cost and weight of concrete can be reduced. B. Advantages The cost reduction can be achieved by the usage of locally available alternative materials, instead of conventional materials and the weight of the concrete can be reduced by using manufactured plastic coarse aggregate, fly ash instead of cement. C. Future Need/Demand The consumption of fine aggregate in concrete production is very high throughout the world , and several developing countries have facing difficulties in meeting the supply of natural fine aggregate in order to satisfy the increasing needs of infrastructural development in recent years. To the solution for the stress and demand for river fine aggregate, researches have being conducted and an alternative materials such as fly ash, slag, limestone powder and siliceous stone powder is been made used. D. Execution The attempts for the replacement of river sand by quarry dust have been made in India. Quarry dust, the waste material that causes disposal problem is made as a valuable resource by the successful utilization of this quarry dust as a fine aggregate and this will also overcome the strain on supply of river sand as fine aggregate and also the cost will be reduced. To evaluate the possibilities of replacement of plastic coarse aggregate with the replacement of quarry dust and flyash as a replacement of fine aggregate and cement.
