Anti-cracking pipe gallery concrete
The invention provides an anti-cracking pipe gallery concrete. The pipe gallery concrete is prepared from the following raw materials in parts by weight: 18-20 parts of cement, 32-34 parts of sand, 29-31 parts of stone, 1-3 parts of fly ash, 0.1-0.3 part of water reducing agent, 6-8 parts of water, 0.03-0.05 part of anti-cracking material and 0.01-0.03 part of polypropylene fiber, wherein the anti-cracking material is prepared from the following components in parts by weight: 75-85 parts of calcium carbonate, 1-6 parts of magnesium carbonate, 5-6 parts of bone glue powder, 0.1-0.5 part of zincoxide, 5-15 parts of stearic acid and 0.1-0.5 part of polyethylene glycol. With application of the anti-cracking pipe gallery concrete, the number of cracks of the pipe gallery wall can be effectively reduced, the bearing capacity and the durability of the structure are improved and the later maintenance cost is reduced.
本发明提供了一种抗开裂的管廊混凝土。该管廊混凝土，以重量份数计，其原料包括：18～20份水泥，32～34份沙子，29～31份石子，1～3份粉煤灰，0.1～0.3份减水剂，6～8份水，0.03～0.05份抗裂材料，0.01～0.03份聚丙烯纤维；其中，所述抗裂材料包括如下重量份数的下列组分：碳酸钙75‑85份、碳酸镁1‑6份、骨胶粉5‑6份、氧化锌0.1‑0.5份、硬脂酸5‑15份和聚乙二醇0.1‑0.5份。应用本发明可以有效地减少管廊墙体的开裂数量，提高结构的承载能力和耐久性能，减少后期的维护成本。
