High-performance premixed concrete and preparation method thereof
The invention relates to the field of concrete preparation, and discloses high-performance premixed concrete, which is prepared from the following components in parts by mass: 180 to 220 parts of water, 120 to 150 parts of cement, 250 to 300 parts of mixed sand, 500 to 600 parts of fine aggregate, 700 to 900 parts of coarse aggregate, 100 to 150 parts of fly ash, 20 to 30 parts of silane coupling agent, 10 to 12 parts of thickening agent, 10 to 15 parts of antifreezing agent, 5 to 8 parts of toughening agent, 2 to 3 parts of water reducing agent and 50 to 80 parts of inorganic filler. The reinforcing agent slurry composed of the silane coupling agent, the thickening agent, the anti-freezing agent, the toughening agent and the water reducing agent is added into the raw materials, the physical performance of the premixed concrete can be greatly improved, meanwhile, the time sensitivity of the premixed concrete is reduced, the aging time of the working performance can be prolonged by about 3-5 hours, and the inorganic filler is added into the raw materials, so that the environment-friendly performance of the premixed concrete is improved. According to the invention, the raw material cost is low, the preparation process is simple, convenient and rapid, and the use requirements are better met.
本发明涉及混凝土制备领域，公开了一种高性能预拌混凝土，按质量份数包括以下组成成分：水180‑220份、水泥120‑150份、混合砂250‑300份、细骨料500‑600份、粗骨料700‑900份、粉煤灰100‑150份、硅烷偶联剂20‑30份、增稠剂10‑12份、防冻剂10‑15份、增韧剂5‑8份、减水剂2‑3份、无机填料50‑80份。本发明通过在原料中增加由硅烷偶联剂、增稠剂、防冻剂、增韧剂和减水剂组成的增强剂浆液，可以极大的提高预拌混凝土的物理性能，同时降低预拌混凝土的时间敏感性，可延长工作性能的时效时间约三至五小时，且在原料中加入无机填料，提高预拌混凝土的抗压强度和抗裂性能，增加适应性范围，本发明原料成本低，制备过程简单方便快速，更好地满足使用需求。
