The invention discloses a precast concrete module for a bridge. The precast concrete module is prepared from the following raw materials in percentage by mass: 50-60% of cement, 20-40% of sand, 5-10% of stones, 8-12% of fly ash, 4-8% of mica powder and 5-10 amp of limestone. 2-8% of filling fibers, 2-5% of composite carbon fibers, 2-5% of expanded perlite, 2-4% of a rock polycarboxylic acid high-performance water reducing agent, 3-5% of an air entraining agent, 3-5% of a foaming agent, 1-3% of a coagulant and 20-50% of water are put into stirring equipment to be stirred, and then the mixture is poured into a shaping module to be solidified. After the mica powder, the filling fibers, the composite carbon fibers and the expanded perlite are blended according to a proper proportion and fully stirred and mixed, when the concrete module is solidified, gaps in the concrete module can be filled, the effect of reinforcing ribs is achieved, the situation that the concrete module cracks in a severe environment can be effectively avoided, and the service life of the concrete module is prolonged. And the anti-freezing property is good.
本发明公开了一种桥梁预制混凝土模块，由以下质量份的原料:水泥50‑60％、砂20‑40％、石子5‑10％、粉煤灰8‑12％、云母粉4‑8％、石灰岩5‑10&、填充纤维2‑8％、复合碳纤维2‑5％、膨胀珍珠岩2‑5％、岩聚羧酸高性能减水剂2‑4％、引气剂3‑5％、发泡剂3‑5％、凝结剂1％‑3％和水20‑50％投入到搅拌设备内搅拌完成后，接着浇筑到定型模块中凝固而成。本发明通过云母粉、填充纤维、复合碳纤维和膨胀珍珠岩，适当比例进行调配通过搅拌混合充分后，在混凝土模块凝固时，能够将混凝土模块中的间隙填充，并起到加强筋的作用，能够有效的避免混凝土模块在恶劣环境下开裂的情况，并具备良好的抗冻性。
