YND-101、102 新型混凝土减水防冻剂研制

RESEARCH ON YND101 AND YND102 ANTIFREEZING ADMIXTURES FOR CONCRETE

ＹＮＤ—１０１和ＹＮＤ－１０２是根据三北地区的气候特点研究的－１０℃混凝土减水防冻剂，由于采用了具有防冻、早强和阻锈等多种功能的新型组分，大幅度地降低了防冻剂的掺量和碱引入量，不会促进砼的碱－骨料反应，且具有良好的负温早强、增强效果。

Based on the weather characteristic of the north,northwest and northeast regions of China,a kind of waterreduce antifreezing admixture for 10℃ is madeThe agent is consist of antifreezing,accelerate and resistant steel corrosion compositionIt can reduce the dosage by cement weight and has a little alkali content without accelerating AAR for concreteThis admixture has a good effect on increasing strength at the early for concrete at minustemperature
