Anti-cracking recycled concrete for engineering construction and preparation method of concrete
The invention discloses anti-cracking recycled concrete for engineering construction and a preparation method of the concrete, and the anti-cracking recycled concrete comprises the following components in parts by mass: 35-55 parts of recycled aggregate, 60-85 parts of natural aggregate, 10-20 parts of water, 1-3 parts of a water reducing agent, 15-20 parts of cement, 6-9 parts of silicon powder, 10-15 parts of textile fiber, 6-9 parts of calcium chloride and an expanding agent. According to the invention, mutual entanglement among molecules is facilitated to form a net structure, so that the cohesive force of cement slurry to recycled aggregate and natural aggregate is enhanced, the adhesion of the slurry is enhanced, the cohesive force of concrete slurry is enhanced under cooperation of textile fibers and aluminum silicate ceramic fibers, and the expanding agent is added into the recycled concrete slurry, the performance of the concrete slurry itself is improved, high crack resistance and seepage resistance are achieved, tensile stress generated by cement shrinkage can be balanced, the strength of the recycled concrete is enhanced, the effect of preventing the concrete from cracking is achieved, and the situation that the concrete cracks is avoided.
本发明公开了一种工程建设用防开裂再生混凝土及其制备方法，包括以下质量份数的组分：再生集料35‑55份、天然骨料60、85份、水10‑20份、减水剂1‑3份、水泥15‑20份、硅粉6‑9份、纺织纤维10‑15份、氯化钙6‑9份以及膨胀剂，本发明利于分子之间的互相缠结以形成网状结构，使得水泥浆液对再生集料以及天然骨料的粘结力增强，加强了浆料的粘附性，且在纺织纤维、硅酸铝陶瓷纤维的配合下，使得混凝土浆料的粘结力加强，且在再生混凝土浆料内添加有膨胀剂，使得混凝土浆料自身性能提升，具有良好的抗裂防渗性，可以平衡水泥收缩产生的拉应力，使得再生混凝土的自身强度进行加强，从而起到防止混凝土开裂的作用，规避了混凝土出现开裂的状况。
