Use Of Recycled Aggregate In Concrete
1.2 Advantages of recycling of construction materials -: Used for construction of precast & cast in situ gutters &kerb‟s. Cost saving: - There are no detrimental effects on concrete & it is expected that the increase in the cost of cement could be offset by the lower cost of Recycled Concrete Aggregate (RCA).

Mix Design for Pervious Recycled Aggregate Concrete
The water absorption for 20 and 13 mm recycled concrete aggregates was 5.3 and 8.2 %, respectively, compared to 1.0 % for the natural aggregate. High water absorption and lower specific gravity for 13 mm recycled concrete aggregate are due to increased amount of weak attached mortar compared to that for 20 mm recycled …

Use of Recycled Aggregate in Concrete Seminar Report pdf
The utilization of recycled aggregate is particularly very promising as 75 per cent of concrete is made of aggregates. In that case, the aggregates considered are slag, power plant wastes, recycled concrete, mining and quarrying wastes, waste glass, incinerator residue, red mud, burnt clay, sawdust, combustor ash and foundry sand.
