摘要
通过对添加WHⅡ型超缓凝剂的水泥和混凝土的试验研究发现:WHⅡ型超缓凝剂延缓了水泥早期的水化热的释放,降低了混凝土的干缩,对钢筋锈蚀、混凝土抗冻融性能等方面无不利影响,从而提高了混凝土的耐久性能.
By the experiments of adding WHⅡsuper retarder to cement and concrete, it is found that WHⅡsuper retarder slackens early releasing of hydration heat of the cement, reduces drying shrinkage of concrete, and has no negative effect on corrosion of steel in concrete and freeze-thaw resistance of concrete, and finally improves durability of concrete.
