摘　　要：针对目前抗硫酸盐单组分混凝土外加剂制备过程较为繁琐,成本较高、效果不理想、时效性短、影响其它相关性能等诸多问题,在确定单组分外加剂添加效果的基础上,将不同作用多组分抗硫酸盐侵蚀试剂进行复配,制备复合抗硫酸盐侵蚀混凝土外加剂,并对其性能和微观结构进行研究。结果表明,所制备的复合外加剂主要性能指标符合JC/T 1011—2006《混凝土抗硫酸盐类侵蚀防腐剂》要求。In view of the problems of complicated preparation process,high cost,unsatisfactory effect,short time-effect and reducing other performance by adding single-component concrete sulfate-resistant admixture,in this paper,on the basis of determining the adding effect of single-component admixtures,multi-component sulfate-resistant reagents with different effects are compounding.The sulfate attack admixture was prepared and its properties and microstructure were studied.The main performance indexes of the admixture meet the requirements of relevant standard JC/T 1011—2006"Sulfate corrosion-resistance admixtures for concrete".
