A comparative study of recycled aggregates from concrete and mixed debris as material for unbound road sub-base Seven different types of recycled aggregates from construction and demolition waste (CDW) have been evaluated as granular materials for unbound road sub-bases construction.
After the initial studies, concrete blocks were molded with the following dimensions: 100x190x390 mm). Studies have determined the behavior of aggregates in relation to mold humidity specific mass, water absorption, and compression resistance in view of the percentage of recycled debris that composes the total aggregate.
Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete. The recycled concrete aggregates have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates.
