摘要
聚羧酸系外加剂在高强高性能混凝土中的应用已被业界人士所熟知,但是在预拌混凝土企业中,在全部等级的混凝土中的应用,在国内目前只此一家。瑞科尔建筑材料(天津)有限公司在试验和生产过程中很好的解决了聚羧酸系外加剂在普通混凝土尤其是在低强度、低坍落度混凝土中应用存在的技术和经济方面的问题。本文介绍了聚羧酸类外加剂对水泥适应性及混凝土性能的影响并对聚羧酸系外加剂的减水机理和在混凝土中所体现出的优势,以及存在的问题进行了详细的论述。
Although the wide application of Polyearboxylates （PC） admixture in high-strength anti high performance concrete has been well known by the entire industry, the manufacturer who can make it applied in various pre-mixed concrete strength levels is extremely rare. Rinker Materials （Tianjin） Co., Ltd. is just the originator, who successfully solved hoth technical and economical problems of PC admixture applications in normal concrete, especially low strength and low slump pre-mixed concrete, and this success results from precise trials and actual production practice. This article makes introduction about the influence on cement workability and concrete performance given by PC admixture, also thoroughly analyses the advantages of its water-reduction effect in concrete application and possible side-effects.
