Recycling of Concrete by Partial Replacement of Heat Processed Waste Aggregate

Concrete is the second highest abandon material on the earth surface after water, it is inorganic in nature therefore it can be a big cause of the construction inorganic unsustainability by accumulating solid waste on the earth surface, in concrete coarse aggregate is the major component of the concrete hence in this research work recycled concrete made with the heat processed used coarse aggregate in first generation concrete, it is qualitative work so it is concentrated on the strength and durability of the concrete made of the partial replacement of the heat processed coarse aggregate, first generation concrete can be further utilize as the second generation by heat and mechanical treatment, mortar starts loosing the bonding between cement and aggregate temperature above 3000C, in this research work recycling of aggregate from waste concrete chunks are heat treated and mechanical rubbing optimum utilization of this recycled aggregate is achieved 15% possible replacement of conventional aggregate with the heat processed aggregate.
