Abstract

The recycled aggregates were modified by sodium silicate, cement grout, cement mixed with superfine fly ash grout and polymer emulsion. The influence of the modified recycled aggregates to the mechanical properties of the concrete was studied. The results indicated that the recycled aggregates can reduce the compressive strength, split tensile strength and elasticity modulus. The modified process of the recycled aggregates can enhance the mechanical properties of the concrete. The early split tensile strength and elasticity modulus were preferably enhanced by sodium silicate. The cement grout and cement mixed with superfine fly ash grout can significantly improved the later mechanical properties.
