Preparation method of recycled brick-concrete aggregate pervious concrete
The invention discloses a preparation method of recycled brick-concrete aggregate pervious concrete. The method comprises the following steps of: carrying out screening treatment, water flotation impurity removal treatment and drying collection on recycled brick-concrete aggregate to prepare available recycled brick-concrete aggregate, pre-wetting the recycled brick-concrete aggregate, adding thepre-wetted recycled brick-concrete aggregate and natural stones into a stirrer, adding 50% of weighed mixing water into the stirrer, and stirring for 30 seconds; sequentially pouring weighed medium sand and cement into the stirrer, continuously stirring for 30 seconds, finally uniformly mixing the weighed water reducing agent with the residual 50% of mixing water, pouring the mixture into the stirrer, and stirring for 3 minutes to obtain uniformly-stirred recycled brick-concrete pervious concrete. According to the invention, effective recycling of the building brick-concrete waste is realized,the loss of natural stone resources is reduced, the recycling rate of renewable resources is improved, and the mechanical property strength of later-stage formed concrete is improved.
本发明公开了一种再生砖混骨料透水混凝土的制备方法，通过对再生砖混骨料进行筛选处理、水浮法去杂质处理与烘干收集，将其制备成可用的再生砖混骨料，将再生砖混骨料预先润湿后和天然石子一同加入搅拌机内，再将称取拌合水的50%加入搅拌机内搅拌30s；再将称取的中砂和水泥先后倒入所述的搅拌机中继续搅拌30s，最后将称取的减水剂与剩余的50%拌合水混合均匀后一并倒入所述搅拌机中搅拌3min，得到搅拌均匀的再生砖混透水混凝土；本发明实现了建筑砖混废料的资源化有效再利用，减少天然石子资源的损耗并提高再生资源回收利用率，提高了后期成型混凝土的力学性能强度。
