High-strength recycled concrete and production process thereof
The invention discloses high-strength recycled concrete and a production process thereof. The high-strength recycled concrete comprises the following components in parts by mass: 600-800 parts of recycled aggregate, 40-70 parts of fly ash, 230-330 parts of cement, 60-130 parts of slag powder, 8-12 parts of a concrete reinforcing agent, 5-8 parts of reinforced fibers, 2.5-4.5 parts of a water reducing agent, 0.01-0.5 part of a retarder and 3-6 parts of a UEA expanding agent, with the balance being water. According to the invention, alkali metal silicate, wooden sulfonate, diethylenetriamine and saturated lime water are added into the concrete reinforcing agent, so a stable net-shaped structure is formed in the concrete added with the concrete reinforcing agent, the workability of the concrete is effectively improved, the strength of the concrete is improved, and the concrete meets a national harmful substance requirement standard in China. According to the prepared concrete, the uniformity and the stability of the overall structural strength of the concrete are effectively improved under the simultaneous action of the reinforced fibers and the concrete reinforcing agent.
本发明公开了一种高强度再生混凝土及其生产工艺，包括质量份比如下的成份：再生骨料600～800份、粉煤灰40～70份、水泥230～330份、矿渣粉60～130份、混凝土增强剂8～12份、增强纤维5～8份、减水剂2.5～4.5份、缓凝剂0.01～0.5份、UEA膨胀剂3～6份和余量水，本发明通过在混凝土增强剂内添加碱金属硅酸盐、木制磺酸盐、二乙烯三胺和饱和石灰水，使得添加混凝土增强剂的混凝土内部形成稳定的网状结构，有效的提高混凝土和易性、增加混凝土强度，且混凝土符合国家有害物质要求标准，本发明制备的混凝土利用增强纤维和混凝土增强剂同时作用下，有效的提高混凝土整体结构强度的均匀性和稳定性。
