Freeze-thaw-resistant concrete admixture and freeze-thaw-resistant concrete using same
The invention relates to a freeze-thaw-resistant concrete admixture and freeze-thaw-resistant concrete using the same. The admixture comprises rubber powder, sodium sulfate, ethylene glycol, sodium formate, a polycarboxylate superplasticizer and lignocellulose. The concrete comprises cement, fly ash, nickel powder, nickel stone, common stone, sand, water, an air entraining agent, an expanding agent and a freeze-thaw-resistant admixture. According to the invention, the nickel powder and the nickel stones are used for replacing stones, so that the cost is greatly reduced; the freeze-thaw resistance is good and durable, the strength is high, and the manufacturing process is simple; the durability is good; and complementation and grading of the advantages of the composite multifunctional components are achieved, optimization is achieved, the internal structure of the concrete is compact, and the freeze-thaw resistance is improved.
本发明涉及一种抗冻融混凝土外加剂及使用该外加剂的抗冻融混凝土，该外加剂包括橡胶粉、硫酸钠、乙二醇、甲酸钠、聚羧酸减水剂和木质纤维素；该混凝土包括水泥，粉煤灰，镍粉，镍石子，普通石子，砂子，水，引气剂，膨胀剂和抗冻融外加剂；本发明中使用镍粉及使用镍石子代替石子，大大减少成本；抗冻融性能好、持久，强度高，制作工艺简单；耐久性好；实现复合多功能组分优势互补与级配，优化，混凝土内部结构密实，提高了抗冻融性能。
