Fiber concrete and preparation method thereof
The invention discloses a fiber concrete and a preparation method thereof, and relates to the technical field of concretes. The fiber concrete comprises, by weight, 450-500 parts of cement, 250-300 parts of water, 1000-1200 parts of fine stone, 200-400 parts of sand, 60-80 parts of fly ash, 100-120 parts of mineral powder, 5-6 parts of a water reducing agent, 5-10 parts of calcium lactate, 1-5 parts of a repairing agent and 50-100 parts of reinforced fibers; and the repairing agent is obtained by immobilizing bacillus cohnii on expanded perlite. The fiber concrete prepared by the invention hasthe advantages of high impermeability and high mechanical strength.
本发明公开了一种纤维混凝土及其制备方法，涉及混凝土技术领域。其技术要点是：该纤维混凝土包括如下重量份数的组分：水泥：450‑500份；水：250‑300份；细石：1000‑1200份；砂子：200‑400份；粉煤灰：60‑80份；矿粉：100‑120份；减水剂：5‑6份；乳酸钙：5‑10份；修复剂：1‑5份增强纤维：50‑100份；所述修复剂由膨胀珍珠岩固载科氏芽孢杆菌得到。本发明制备得到的纤维混凝土具有高抗渗性、高力学强度的优点。
