In-situ reinforcement method of recycled aggregate
The invention discloses an in-situ reinforcement method of a recycled aggregate; the method comprises that concrete containing the recycled aggregate is stirred and mixed and subjected to in-situ reinforcement, wherein the concrete comprises raw materials of an admixture, cement, a coarse aggregate, a fine aggregate and water. The method is characterized by comprising the steps: firstly, stirring all the admixture and half of the mass of water for 10-20 s, then adding all the coarse aggregate and all the fine aggregate, stirring for 10-20 s, next adding all the cement, stirring for 20-40 s, finally adding the remaining half of the water, continuing to stir for 30-60 s, and thus obtaining the in-situ reinforced recycled aggregate concrete mixture. The recycled aggregate concrete prepared by the process can achieve in-situ reinforcement of the recycled aggregate, and the compressive strength of the recycled aggregate concrete can be effectively improved.
