High-impermeability durable concrete for underground structure
The invention relates to concrete with high impermeability and durability for an underground structure, which is prepared from the following raw material components: cement, coarse aggregate, fine aggregate, ground stone powder, a water reducing agent and water, and also comprises a low-porosity impermeable auxiliary agent and a calcium maintaining agent, the concrete is prepared from the following raw material components according to the use amount of a single component ratio: 150 to 200kg of cement, 400 to 500kg of coarse aggregate, 600 to 700kg of fine aggregate, 100 to 150kg of ground stone powder, 2.2 to 2.6 kg of a water reducing agent and 100 to 120kg of water. The concrete further comprises the following components according to the dosage of a single formula: 3.2 to 3.6 kg of a low-porosity anti-seepage auxiliary agent and 70 to 100 kg of a calcium maintaining agent. The high-impermeability durable concrete for the underground structure has excellent mechanical strength required by a base material of a large-scale structure; the anti-seepage performance is excellent, and the very high long-term use stability can be kept when the anti-seepage concrete is used in an underground environment.
一种地下结构用高抗渗耐久性混凝土,其原料成分由水泥、粗骨料、细骨料、磨细石粉、减水剂和水组成,所述原料成分还包括低孔隙率防渗助剂和钙质维持剂;所述的混凝土成分按照单方配比用量计,各原料成分用量如下:水泥150‑200kg、粗骨料400‑500kg、细骨料600‑700kg、磨细石粉100‑150kg、减水剂2.2‑2.6kg和水100‑120kg;所述的混凝土成分按照单方配比用量计,还包括如下用量的成分:低孔隙率防渗助剂3.2‑3.6kg和钙质维持剂70‑100kg。本发明的地下结构用高抗渗耐久性混凝土具备作为大型构筑物基体材料要求的优良的机械强度;具备优良的抗渗性能,使用在地下环境时可保持非常高的长期使用稳定性。
