High-strength anti-crack concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-strength anti-crack concrete and a preparation method thereof. The high-strength anti-crack concrete is prepared from the following raw materials by weight: 28-36 parts of Portland cement, 9-13 parts of fly ash, 2.5-4 parts of silica fume, 29-33 parts of river sand, 55-75 parts of gravel, 0.2-0.7 part of a compound water reducer, 4-15 parts of an anti-crack crystallizing agent, 7-9 parts of sodium monofluorophosphate, and 25-27 parts of water. According to the high-strength anti-crack concrete, the anti-crack performance and the overall strength of the concrete are improved.
本申请涉及混凝土技术领域，具体公开了一种高强抗裂混凝土及其制备方法，其由包括如下重量份的原料制备而成：硅酸盐水泥28‑36份，粉煤灰9‑13份、硅灰2.5‑4份、河砂29‑33份、碎石55‑75份、复配减水剂0.2‑0.7份、抗裂结晶剂4‑15份、单氟磷酸钠7‑9份、水25‑27份。本申请的高强抗裂混凝土提升了混凝土的抗裂性能和整体强度。
