High-strength quick-setting concrete repairing material as well as preparation method and application thereof
The invention discloses a high-strength quick-setting concrete repairing material, which is prepared from the following raw materials in parts by weight: 0 to 5 parts of basalt chopped fibers, 0 to 5 parts of chopped carbon fibers, 35 to 400 parts of sulphoaluminate cement, 25 to 400 parts of Portland cement, 10 to 25 parts of anhydrite, 10 to 25 parts of silica fume, 10 to 35 parts of fly ash, 10 to 25 parts of expanding agents, 8 to 35 parts of redispersible latex powder, 450 to 560 parts of quartz sand and 2 to 5 parts of water reducing agents. The concrete is prepared from the following components in parts by weight: 1-2 parts of a foaming agent, 0.2-1.2 parts of a coagulation accelerator, 0-0.8 part of a retarder, 0.6-2 parts of a dry powder defoaming agent and 0-0.6 part of hydroxypropyl methyl cellulose. According to the invention, the basalt chopped fibers and the chopped carbon fibers are used as main reinforcing materials, and the quick-hardening cement is added to interact with various auxiliary materials, so that the product has the advantages of super early strength, short construction period, automatic leveling function, high fracture resistance, high strength, freeze-thaw damage resistance and long service life.
本发明公开了一种高强速凝混凝土修补材料，包括以下重量份的原料：玄武岩短切纤维0‑5份，短切碳纤维0‑5份，硫铝酸盐水泥35‑400份，硅酸盐水泥25‑400份，硬石膏10‑25份，硅灰10‑25份，粉煤灰10‑35份，膨胀剂10‑25份，可再分散乳胶粉8‑35份，石英砂450‑560份，减水剂2‑5份，促凝剂0.2‑1.2份，缓凝剂0‑0.8份，干粉消泡剂0.6‑2份，羟丙基甲基纤维素0‑0.6份。本发明将玄武岩短切纤维与短切碳纤维作为主要增强材料，加入快硬水泥与多种辅料相互作用，产品超早强性能，施工周期短，具有自动找平功能、高抗折、高强、抗冻融破坏、使用寿命长。
