Clean recycled aggregate produced from construction waste and preparation method thereof
The invention relates to the field of reutilization of building materials, and particularly discloses a clean recycled aggregate produced from building wastes and a preparation method of the clean recycled aggregate. Comprising the following raw materials in parts by weight: 200-300 parts of construction waste raw slag, 100-120 parts of vinyl acetate-ethylene copolymer emulsion, 2-4 parts of covalent organic frameworks (COFs), 20-30 parts of nano carbon black, 10-15 parts of boric acid ester and 20-60 parts of a coupling agent. The preparation method comprises the following steps: crushing the construction waste into recycled aggregate raw slag, reinforcing the recycled aggregate raw slag, and grading according to the size to obtain a coarse aggregate and a fine aggregate; the recycled aggregate obtained by the invention is high in strength performance and small in water absorption rate, can meet the requirements of preparing recycled aggregate concrete with higher mechanical properties, reasonably utilizes the construction waste, and is an environment-friendly building material.
本申请涉及建筑材料再利用领域，具体公开了一种利用建筑垃圾生产的洁净再生骨料及其制备方法。包括以下原料：建筑垃圾原渣200‑300份，醋酸乙烯‑乙烯共聚乳液100‑120份，共价有机骨架COFs 2‑4份，纳米炭黑20‑30份，硼酸酯10‑15份，偶联剂20‑60份；制备方法为：将建筑垃圾粉碎为再生骨料原渣，对再生骨料原渣进行补强处理，按大小分级即得粗细两种骨料；本申请得到的再生骨料强度性能高、吸水率小，可满足制备更高力学性能再生骨料混凝土的要求，合理利用建筑垃圾，是一种环境友好型的建筑材料。
