Anti-crack and anti-corrosion mass concrete for underground space and preparation method of anti-crack and anti-corrosion mass concrete
The invention relates to the technical field of concrete, and particularly discloses underground space anti-crack and anti-corrosion mass concrete and a preparation method thereof. The invention discloses anti-crack and anti-corrosion mass concrete for underground space. The anti-crack and anti-corrosion mass concrete is prepared from 320 to 335 parts of cement, 76 to 88 parts of fly ash, 1025 to 1050 parts of coarse aggregate, 670 to 685 parts of fine aggregate, 11 to 15 parts of carbon fiber, 14 to 17 parts of graphite particles, 4 to 6 parts of anti-permeability agent, 2 to 3 parts of water reducing agent and 155 to 170 parts of water, the anti-permeability agent is prepared by mixing polyethylene glycol distearate, diethanolisopropanolamine and D-mannitol according to the mass ratio of (2 to 4): (1 to 2): (1 to 2). The mass concrete prepared by the invention has good crack resistance and erosion resistance, can effectively control the generation of cracks under the condition of not adding an expanding agent, and can be widely applied to underground space engineering such as underground stations, tunnels, basements and the like.
本发明涉及混凝土技术领域，具体公开了一种地下空间抗裂抗腐蚀大体积混凝土及其制备方法。一种地下空间抗裂抗腐蚀大体积混凝土包括320~335份水泥、76~88份粉煤灰、1025~1050份粗集料、670~685份细集料、11~15份碳纤维、14~17份石墨颗粒、4~6份抗渗剂、2~3份减水剂和155~170份水；抗渗剂是聚乙二醇二硬脂酸酯、二乙醇单异丙醇胺和D‑甘露糖醇以（2~4）：（1~2）：（1~2）的质量比混合而成的。本申请所制备的大体积混凝土具备良好的抗裂性和抗侵蚀性，在不添加膨胀剂的情况下，也可以有效控制裂缝的产生，可广泛应用于地下车站、隧道、地下室等地下空间工程中。
