Tunnel lining corrosion-resistant concrete
The invention belongs to the technical field of building materials and relates to a tunnel lining corrosion-resistant concrete. The tunnel lining corrosion-resistant concrete is prepared from the following raw materials in parts by mass: 1 part of a gelling component; 0.40 to 0.50 part of a compactness improving component; 0.90 to 1.00 part of a corrosion-resistant component; 0.018 to 0.024 part of a construction performance regulating component; and 6.40 to 6.80 parts of aggregate. All the components are added in sequence and stirred for 3-5 min through a forced concrete stirrer, so that theconcrete mixture is prepared. The tunnel lining corrosion-resistant concrete is moderate in expansion degree and gas content; and a complex die cavity of a steel bar network can be intelligently filled according to the gravity of the tunnel lining corrosion-resistant concrete. After concrete pouring is completed, hydration temperature rise is small, the hardened concrete is high in permeation resistance and high in resistance to erosion of various ions, and the concrete is extremely suitable for railway engineering tunnel lining structures in complex and harsh environments and also suitable for engineering underground structures of roads, mining, subways and the like.
本发明属于建筑材料技术领域，具体涉及一种隧道衬砌耐腐蚀混凝土，按原材料质量份数计，其特征在于，胶凝组分：密实性提升组分：耐腐蚀组分：施工性能调控组分：骨料=1：（0.40‑0.50）：（0.90‑1.00）：（0.018‑0.024）：（6.40‑6.80）。各组分按次序添加，采用强制式混凝土搅拌机搅拌3‑5min，制得混凝土拌合物。本发明所述的隧道衬砌耐腐蚀混凝土扩展度和含气量适中，能够依据自身重力智能填充钢筋网络复杂的模腔。混凝土浇筑完成后水化温升小，硬化后混凝土抗渗透性能高，抵抗各类离子侵蚀能力强，极其适用于复杂严酷环境下铁路工程隧道衬砌结构，也适用于公路、采矿、地铁等工程地下结构。
