Steam-curing-free concrete for C40 prefabricated component and preparation method of steam-curing-free concrete
The invention discloses steam-curing-free concrete for a C40 prefabricated component and a preparation method of the steam-curing-free concrete. Each cubic meter of the concrete comprises the following raw materials in parts by mass: 305-315 parts of Portland cement, 8-16 parts of sulphoaluminate cement, 52-55 parts of fly ash, 5-7 parts of anhydrous sodium sulfate, 1020-1040 parts of stone, 810-830 parts of medium sand, 4.3-4.7 parts of a water reducing agent and 145-165 parts of water. The 1d compressive strength of concrete prepared from the material is greater than 23.3 MPa. The steam-curing-free concrete can improve the early strength of the concrete, is good in construction performance, can improve the mold turnover rate, accelerates the production progress, shortens the construction period, and is wide in raw material source and reasonable in price.
本发明公开了一种C40预制构件用免蒸养混凝土及其制备方法，该混凝土中的原材料每立方米按质量份计如下：硅酸盐水泥305‑315份、硫铝酸盐水泥8‑16份、粉煤灰52‑55份、无水硫酸钠5‑7份、石子1020‑1040份、中砂810‑830份、减水剂4.3‑4.7份、水145‑165份，所述材料制得的混凝土1d抗压强度大于23.3MPa。本发明免蒸养混凝土可提高混凝土的早期强度，施工性能良好，并可提高模具周转率，加快生产进度缩短工期，并且原材料来源广泛、价格合理。
