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 Limestone, incinerator residue, red mud, burnt clay, sawdust, combustor ash and foundry sand.
