High-strength impervious self-compacting concrete for pipe gallery box culvert and preparation method thereof
The invention discloses high-strength impervious self-compacting concrete for a pipe gallery box culvert and a preparation method of the high-strength impervious self-compacting concrete, and belongs to the technical field of concrete. The anti-cracking waterproof mortar comprises the following components in parts by weight: 200-300 parts of medium-coarse sand, 300-400 parts of cement, 400-600 parts of water, 100-200 parts of gravel, 80-100 parts of fly ash, 60-80 parts of a stabilizing composition and 70-90 parts of an anti-seepage additive, wherein the stabilizing composition is prepared by mixing the following components in parts by weight: 25-30 parts of calcium formate, 20-30 parts of a composite fiber anti-cracking agent and 15-20 parts of an expansion fiber anti-cracking waterproof agent. The anti-seepage admixture is prepared by mixing the polypropylene reticular fiber, the anti-seepage fiber and the glass fiber reinforced plastic fiber, the reticular structure of the polypropylene reticular fiber can be damaged during stirring to form single fibers, and the single fibers are mixed, so that the anti-seepage performance of the concrete is improved; the anti-seepage fibers and the glass fiber reinforced plastic fibers can further improve the anti-seepage performance of the concrete.
本发明公开了一种管廊箱涵用高强抗渗自密实混凝土及其制备方法，属于混凝土技术领域。本发明包括以下重量份的组分：200‑300份中粗砂、300‑400份水泥、400‑600份水、100‑200份碎石、80‑100份粉煤灰、60‑80份稳固组合物和70‑90份防渗外加剂，稳固组合物由以下重量份的组分混合而成：25‑30份甲酸钙、20‑30份复合纤维抗裂剂和15‑20份膨胀纤维抗裂防水剂。本发明采用聚丙烯网状纤维、防渗纤维和玻璃钢纤维混合制成防渗外加剂，聚丙烯网状纤维的网状结构会在搅拌中得到破坏，形成单纤维，这些单纤维错综交杂，提高了混凝土的防渗漏性，防渗纤维和玻璃钢纤维则能够进一步提高混凝土的防渗漏性。
