摘　　要：试验研究证明，ＳＪ－Ｈ１型高效缓凝剂掺量少，缓凝效果强。在硅酸盐水泥混凝土中掺用量为水泥重量的０．１３％时，即可使混凝土的初凝时间推迟５ｈ以上，掺量愈大，缓凝效果愈强，同时还具有一定的减水增强作用。Tests proved that SJ-H1 high range retarding agent could be used in small content with good retarding effect. When its content in Portland cement concrete was 0.13% by weight of cement, initital setting of the concrete could be delayed by over 5 hours, the more the content the better the retarding effect, and likewise had a certain effeet on water reduction and strength gain.
