Concrete for construction of ultra-long concrete structure
The invention is applicable to the technical field of concrete preparation, and provides concrete for construction of an ultra-long concrete structure. The concrete comprising the following raw materials: 220-250 parts of cement, 34-49 parts of modified wollastonite powder, 32-52 parts of mineral powder, 890-1030 parts of fine stone, 82-104 parts of fly ash, 7.9-9.3 parts of a CM-5 type composite anti-freezing high-efficiency water reducing agent, 35-37 parts of an HCSA expanding agent, 11-19 parts of a titanate coupling agent, 22-38 parts of polyester fiber and 10-16 parts of a mixture of aluminum phosphate and aluminum hydroxysulfate. The concrete for construction of the ultra-long concrete structure provided by the embodiment of the invention can improve rheological properties, reduce hydration heat, reduce slump loss, improve the pore structure and mechanical properties of the concrete structure, and improve the later strength and durability.
本发明适用混凝土制备技术领域，提供了一种用于超长混凝土结构施工的混凝土，包括以下原料：水泥220‑250份、改性硅灰石粉34‑49份、矿粉32‑52份、细石890‑1030份、粉煤灰82‑104份、CM‑5型复合防冻高效减水剂7.9‑9.3份、HCSA膨胀剂35‑37份、钛酸酯偶联剂11‑19份、聚酯纤维22‑38份、磷酸铝和硫酸羟铝的混合物10‑16份；本发明实施例提供的用于超长混凝土结构施工的混凝土可以改善流变性能，降低水化热，降低坍落度损失，还可以改善混凝土结构的孔结构和力学性能，提高后期强度和耐久性。
