Concrete for nuclear power station
The invention provides concrete, and particularly relates to concrete for a nuclear power station, which comprises the following components in parts by weight: 10-12 parts of Portland cement, 4-6 parts of fly ash, 30 to 35 parts of river sand, 15-20 parts of broken stone with the particle size of 5-20 mm, 20 to 35 parts of broken stone with the particle size of 21 to 31.5 mm, 6-7 parts of water, 1.01 to 1.05 parts of a water reducing agent and 0.05 to 0.07 part of an air entraining agent, wherein the water reducing agent is a polycarboxylic acid liquid water reducing agent; and the air entraining agent is a polycarboxylic acid liquid air entraining agent. The concrete is reasonable in raw material storage and convenient to produce; as the consumption of cement and other raw materials is reduced, the production cost is lower, and the adiabatic temperature rise of concrete is less than 50 DEG C; and the time required for concrete stirring is reduced, and the production efficiency is higher.
本发明提供一种混凝土，尤其是一种核电站用混凝土，按重量份计，包括硅酸盐水泥10‑12；粉煤灰4‑6；河砂30‑35；粒径为5‑20mm的碎石15‑20；粒径为21‑31.5mm的碎石20‑35；水6‑7；减水剂1.01‑1.05；引气剂0.05‑0.07；所述减水剂为聚羧酸系液体减水剂；所述引气剂为聚羧酸系液体引气剂。本发明混凝土原材料的储备合理，生产方便；由于减少了水泥等原材料的用量，生产成本更低，混凝土绝热温升小于50℃；减少了混凝土搅拌所需时间，且生产效率更高。
