Influence of recycled concrete aggregates on strength ...

2009-2-1  The recycled aggregate concrete has a compressive strength of at least 76% and modulus of elasticity from 60% to 100% of the control mix. Hansen and Narud found that the compressive strength of recycled concrete is strongly correlated with the water–cement ratio of the original concrete if other factors are kept the same. When the water ...
