Study on Production of Concrete Small Hollow Block with Recycled Aggregate

Abstract:

The construction waste was processed into recycled aggregate and was used to substitute for natural aggregate to produce concrete small hollow block with grade of MU7.5. The effect of grain composition, replacement ratios and chemical activator of recycled aggregate on compressive strength of concrete small hollow block was studied. The results shows that through optimized grain composition of recycled aggregate and mixed with appropriate chemical activator, the compressive strength of concrete small hollow block with 100% recycled aggregate can be satisfied with the requirement of MU7.5 concrete small hollow block.
