Recycled concrete formula and preparation method
The invention discloses a recycled concrete formula and a preparation method. The preparation method comprises the following steps: S1, cracking and polishing waste gas concrete blocks to prepare recycled concrete aggregate; s2, small-diameter pebbles with the particle size being 0.5-0.8 mm and medium-diameter pebbles with the particle size being 0.8-1.2 mm are adopted as gravel aggregate together; s3, preparing hollow polypropylene/calcium alginate spheres; s4, preparing a mixture of the component A; s5, preparing a mixture of the component B; and S6, slowly adding the component A mixture into the component B mixture, and continuously stirring to obtain the recycled concrete. On one hand, the problems that a large amount of waste concrete is difficult to treat and the ecological environment is deteriorated increasingly are solved; on the other hand, the construction waste recycled aggregate is used for replacing the natural aggregate, so that the consumption of the natural aggregate in the construction industry can be reduced, the exploitation of the natural gravel is reduced, the problems that the natural aggregate is increasingly deficient and the ecological environment is damaged by exploitation of a large amount of gravel are fundamentally solved, and the living environment of human beings is protected.
本发明公开了一种再生混凝土配方及制备方法，包括以下步骤：S1：将废气混凝土块经裂解、打磨制成再生混凝土骨料；S2：采用粒径为0.5‑0.8mm的小直径石子和粒径为0.8‑1.2mm的中直径石子共同作为碎石骨料；S3：制备空心聚丙烯/海藻酸钙球体；S4：制备A组份混合物；S5：制备B组份混合物；S6：将A组份混合物缓慢加入进B组份混合物中并持续搅拌得到再生混凝土。一方面解决了大量废弃混凝土处理困难以及由此造成的生态环境日益恶化等问题；另一方面，用建筑垃圾循环再生骨料替代天然骨料，可以减少建筑业对天然骨料的消耗，从而减少对天然砂石的开采，从根本上解决了天然骨料的日益匮乏和大量砂石开采对生态环境的破坏，保护了人类的生存环境。
