Reinforcing method of recycled coarse aggregate, obtained reinforced recycled coarse aggregate and concrete
The invention discloses a reinforcing method of recycled coarse aggregate, the obtained reinforced recycled coarse aggregate and concrete, and belongs to the technical field of building materials.The reinforcing method of the recycled coarse aggregate comprises the steps that firstly, the recycled coarse aggregate is placed in a concrete mixer to be mechanically ground and then taken out to be screened, and the physically-reinforced recycled aggregate is obtained; then preparing silica fume slurry, putting the recycled coarse aggregate into the silica fume slurry, and stirring and wrapping the slurry, so as to obtain reinforced recycled coarse aggregate; the preparation method of the recycled concrete comprises the following steps: adding the reinforced recycled coarse aggregate, the stones, the sand, the cement, the water and the polycarboxylate superplasticizer into a concrete mixer according to a mixing process, and stirring to obtain the recycled concrete. The strength of the recycled coarse aggregate can be improved, the performance of the prepared recycled concrete is effectively improved, the treatment strengthening method is simple, aggregate strengthening and concrete mixing connection are compact, and the application range of the recycled aggregate can be expanded.
本发明公开了一种再生粗骨料的强化方法及所得强化再生粗骨料及混凝土，属于建筑材料技术领域，再生粗骨料的强化方法包括首先将再生粗骨料置于混凝土搅拌机中进行机械研磨，取出后过筛，得到物理强化的再生骨料，再调制硅灰浆液，将再生粗骨料置于硅灰浆液中搅拌裹浆，即得到强化的再生粗骨料；再生混凝土的制备方法包括将强化再生粗骨料、石子、砂、水泥、水、聚羧酸减水剂依照拌和流程加入混凝土搅拌机进行搅拌，即得到再生混凝土。本发明能够提高再生粗骨料的强度，使其配制的再生混凝土性能得到有效提高，处理强化方法简单，骨料强化与混凝土拌和衔接紧凑，有利于拓展再生骨料的应用范围。
