混凝土施工时常要用到缓凝剂,缓凝剂的种类很多,糖蜜缓凝剂便是其中的一种。1.糖蜜缓凝剂的掺量及效果糖蜜缓凝剂的适宜掺量为水泥重量的0.2%～0.4%,在气温23～28℃条件下,其掺量每增加0.1%,约可延长凝结时间1h,糖蜜本身也具有减水作用,在上述前提下减水率为5%～8%, Concrete often use retarders, many types of retarders, molasses retarder is one of them. 1. Molasses retarder dosage and effect Molasses retarder appropriate dosage of 0.2% to 0.4% by weight of cement at 23 ~ 28 ℃ temperature conditions, the amount of 0.1% for each additional, about to extend the condensation Time 1h, molasses itself also has a water reducing effect, in the above premise water reduction rate of 5% to 8%
