Abstract

The current recycled concrete is mainly poured by directly taking construction waste after being crushed by classification, cleaned, and gradated as fine and coarse aggregate. The waste is not used according to the classifications of different strength, but is mixed and used uniformly. The impact of recycled aggregate's strength on the strength of recycled concrete is not considered. Aiming at the reinforced concrete of the high-titanium and the blast furnace slag, the effects of construction waste with different strength on recycled concrete of high-titanium slag are studied. By changing the strength of recycled coarse aggregate and design strength, the effects on the compressive performance of recycled concrete are studied. The experiment proves that when the replacement rate is 100% and the design strength is constant, increasing the strength of recycled coarse aggregate properly helps to enhance the strength of recycled concrete. The prepared recycled concrete can be used in road engineering.
