Preparation method of concrete for high-durability prefabricated harbor component
The invention discloses a preparation method of concrete for a high-durability prefabricated harbor component. The concrete is prepared from 300 to 350 parts of Portland cement, 60 to 90 parts of active slag powder, 80 to 100 parts of high-quality fly ash, 25 to 45 parts of silica fume, 300 to 350 parts of 5-10 mm broken stone, 800 to 900 parts of 0-25 mm gravels, 690 to 730 parts of medium sand,5.5 to 6.5 parts of composite air-entraining early-strength polycarboxylic acid high-performance water reducing agent and 150 to160 parts of water. When the concrete for the high-durability prefabricated harbor component is prefabricated, the 56d electric flux is less than or equal to 800 coulomb, the 56d chloride ion migration coefficient is smaller than or equal to 2.5*10<-12> m<2>/s. The concrete for a high-durability prefabricated harbor component has the advantages of being high in solidification speed, good in corrosion resistance, good in acid resistance and alkali resistance and capable of well guaranteeing the service life of construction.
本发明公开了一种高耐久性预制海港构件用混凝土配制方法，包括硅酸盐水泥300‑350份，活性矿渣粉60‑90份，优质粉煤灰80‑100份，微硅粉25‑45份，5‑10mm碎石300‑350份，0‑25mm碎石800‑900份，中砂690‑730份，复合引气早强的聚羧酸高性能减水剂5.5‑6.5份，水150‑160份，在预制高耐久性预制海港构件用混凝土的时候56d电通量≤800库伦，56d氯离子迁移系数≤2.5×10‑12㎡/s，该高耐久性预制海港构件用混凝土配具有凝固速度快，耐腐蚀性好，具有很好的耐酸，耐碱性，能过很好的保证构建的使用寿命。
