Anti-crack fiber concrete and preparation method thereof
The invention discloses anti-crack fiber concrete and a preparation method thereof. The anti-crack fiber concrete is prepared from the following raw materials in parts by weight: 10-30 parts of cement, 15-30 parts of broken stones, 30-50 parts of gravel aggregate, 20-40 parts of water, 20-40 parts of silica fume, 2-3 parts of water reducing agent, 2-6 parts of an expanding agent, 3-6 parts of an anti-cracking agent and 0.3-0.5 part of modified polypropylene fibers. The preparation method is simple, the prepared concrete materials are fully mixed, the dispersion effect is greatly improved, thestructural consistency of the concrete is improved, the shrinkage reducing and cracking preventing performance of the concrete is facilitated, equivalent compensation is conducted on shrinkage of theconcrete, the effects of filling and blocking capillary hole seams are achieved, and the seepage preventing and cracking preventing capacity of the concrete is greatly improved.
本发明公开了一种抗裂纤维混凝土及其制备方法，由以下原料制备而成：所述原料按重量比包括：水泥10‑30份、石子15‑30份、砂石骨料30‑50份、水20‑40、硅灰20‑40、减水剂2‑3份，膨胀剂2‑6份，抗裂剂3‑6份与改性聚丙烯纤维0.3‑0.5份，本发明制备方法简单，所制成的混凝土物料充分混合，分散效果大大提高，提高了混凝土的结构一致性，有利于混凝土的减缩防裂性能，对混凝土的收缩进行等量补偿，并具有填充、堵塞毛细孔缝的作用，极大的提高了混凝土的防渗抗裂能力。
