Constant-temperature curing-free concrete and preparation method thereof
The invention relates to the technical field of concrete materials, and particularly discloses constant-temperature curing-free concrete and a preparation method thereof. The constant-temperature curing-free concrete comprises the following components in parts by mass: 100 parts of water; 255 to 260 parts of cement; 28 to 29 parts of fly ash; 450 to 460 parts of fine aggregate; 625 to 635 parts of coarse aggregate; 30 to 34 parts of a composite humectant; 4.4 to 4.8 parts of an auxiliary agent; the composite humectant is formed by compounding triethanolamine borate, hydroxyethyl urea, sodium pyrophosphate and polyoxyethylene glyceryl ether. The method has the advantage that the concrete can still obtain higher strength without a constant-temperature curing process.
本发明涉及混凝土材料技术领域，具体公开了一种免恒温养护混凝土及其制备方法。免恒温养护混凝土，包括以下质量份数的组分：水100份；水泥255‑260份；粉煤灰28‑29份；细骨料450‑460份；粗骨料625‑635份；复合保湿剂30‑34份；助剂4.4‑4.8份；复合保湿剂为三乙醇胺硼酸酯、羟乙基脲、焦磷酸钠、聚氧乙烯甘油醚的复配。本发明具有使混凝土免除恒温养护工艺依旧能获得较高强度的优点。
