Performance Of Recycled Aggregate Concrete For Structural Applications

Now-a-days cost of construction materials are affecting the economy of all structures. It is a dominating factor affecting environmental housing system around the world. Conventional aggregates namely gravel, and fine aggregate is sand in concrete will be used to control. While natural aggregate is Recycled Aggregate as coarse aggregate will be investigated to replace the aggregate in concrete and Robo sand (Stone dust) as fine aggregate will be replace the sand in concrete. In this investigation, M25 grade of concrete with combination of natural material Recycled Aggregate content as Coarse aggregate in the proportion of 0%,5%,10%,15%,20% & 25% will be replaced and Robo sand (stone dust) as fine aggregate with full 100% replacement of natural sand, sample specimens are prepared and will be tested for workability, compressive strength, split tensile strength and flexural strength for 7,14 and 28 days respectively and also showing the comparative results with Conventional M25 grade concrete. By this project investigation, concrete may be less dense, light weight concrete by Recycled Aggregates and good quality of concrete by Robo sand.
