Anti-static misfire fine aggregate concrete for nuclear power plant and preparation method of anti-static misfire fine aggregate concrete
The invention relates to the technical field of nuclear power engineering, and discloses nuclear power plant anti-static misfire fine aggregate concrete which comprises the following components in parts by mass: 200-400 parts of cement, 300-400 parts of misfire fine aggregate, 300-500 parts of misfire coarse aggregate, 20-50 parts of a composite expanding agent, 50-100 parts of silica fume, 1-3 parts of a water reducing agent and 1-3 parts of an internal curing agent, comprising the following components of the anti-static misfire fine aggregate concrete for the nuclear power plant: the cement is 42.5-grade ordinary cement, and the misfire fine aggregate is limestone or dolomite machine-made sand. According to the anti-static misfire fine aggregate concrete for the nuclear power plant and the preparation method of the anti-static misfire fine aggregate concrete, ordinary cement and silica fume are selected as cementing materials, the concrete has misfire performance, and the raw materials are reasonably graded, so that the concrete is compact and reliable in bearing capacity, and the misfire performance of aggregate is strictly controlled; therefore, the anti-static misfire fine aggregate concrete for the nuclear power plant has the advantages of safe and reliable misfire performance and the like.
本发明涉及核电工程技术领域，且公开了一种核电厂防静电不发火细石混凝土，包括以下核电厂防静电不发火细石混凝土组分及质量份数：水泥200～400份，不发火细骨料300～400份，不发火粗骨料300～500份，复合膨胀剂20～50份，硅灰50～100份，减水剂1～3份，内养护剂1～3份；包括以下核电厂防静电不发火细石混凝土的组成：所述水泥为42.5级普通水泥，不发火细骨料为石灰石质或白云石质机制砂。该核电厂防静电不发火细石混凝土及其制备方法，具备选用普通水泥和硅灰作为胶凝材料，本身具有不发火性能，原材料合理的级配，使得混凝土密实，承载力可靠,而严格控制骨料的不发火性能，使得这种核电厂防静电不发火细石混凝土的不发火性能安全可靠等优点。
