Abstract

The recycled coarse aggregates were soaked in the water-glass solution with several concentrations for different soaking time. The optimal-processing recycled coarse aggregate was used to prepare the recycled concrete whose basic mechanical property and durability were studied. Tests showed: the water-glass solution could significantly reduce the water absorption of recycled coarse aggregate; recycled coarse aggregates treated by the water glass solution of low concentration could significantly increase the compressive strength of recycled concrete. When the recycled coarse aggregates were treated by the water-glass solution with modulus of 3.2 and concentration of 5%, the recycled concrete`s 28d compressive strength increased by 29%, and with excellent durability.
