Anti-cracking concrete and preparation method thereof
The invention relates to the technical field of building materials, in particular to anti-cracking concrete and a preparation method thereof.The anti-cracking concrete is prepared from, by weight, 300-400 parts of cement, 900-1100 parts of pebbles, 300-400 parts of sand, 90-110 parts of fly ash, 30-50 parts of modified calcium oxide expanding agents, 5-15 parts of composite fiber materials and 150 parts of water; the composite fiber material is prepared from a modified polycarboxylate superplasticizer and modified fibers. According to the present invention, through the organic matrix-silane coupling agent-inorganic matrix combination formed by the modified polycarboxylic acid water reducing agent and the modified fiber, the dispersibility of the fiber in the system is improved, and the modified calcium oxide expanding agent is compounded so as to improve the anti-cracking performance of the concrete.
本申请涉及建筑材料技术领域，尤其是涉及一种防开裂混凝土及其制备方法,防开裂混凝土，包括由以下重量份的原料制成：300‑400份水泥、900‑1100份石子、300‑400份砂、90‑110份粉煤灰、30‑50份改性氧化钙类膨胀剂、5‑15份复合纤维材料和150份水；复合纤维材料由改性聚羧酸减水剂和改性纤维制成。本申请通过改性聚羧减水剂与改性纤维形成的有机基体‑硅烷偶联剂‑无机基体的结合体，提高了纤维在体系中的分散性，并同时复配改性氧化钙类膨胀剂，提高了混凝土的防开裂性能。
