Structural Behaviour of Concrete with Partial Replacement Plastic Aggregate and Quarry Dust with Coarse and Fine Aggregate

In this experiment the studies, the strength characteristics of M30 grade concrete 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 gives the final strength parameters such as compressive strength, flexural strength and split tensile strength of the casted cubes, beams and cylinders were tested respectively.
