二、性能 Performance

1 、早强、高强:一天抗压强度达天 3 0 ~ 50MPa ,三天达到 50 ~ 70MPa ,随着养护期龄增长强度不断增长。
   Early strength and high strength : the compressive strength is up to 3 0 ~ 50MPa in one day, and 50 ~ 70MPa in three days, as the maintenance extends, its strength extends.

2 、高抗冻性能:在 0 ~ 10 ℃ 低温使用,早期强度是波特兰水泥的 5 ~ 6 倍; 0 ~ 20 ℃ 加少量外加剂, 3d ~ 7d 强度可达到设计标号的 70 ~ 80% ,冻融循环 300 次强度损失不明显。
   High freeze resistance: it can be used in 0 ~ 10℃ , early strength is 5 ~ 6 times that of ordinary cement; and under 0 ~ 20℃ , it needs a little additional agent. The 3d ~ 7d strength may reach to the 70 ~ 80% of the designed grade, and there is no loss of strength after 300 times of freeze-thaw cycles.

3 、高抗渗性:水泥石结构致密,混凝土抗渗性是同标号硅酸盐水泥的 2 ~ 3 倍。
   Highly seepage resistance: the cement structure is fine and close, the concrete′ s seepage resistance is 3 times that of the same grade silicate cement.

4 、抗碳化性能好,干缩率低。
   Good carbonization resistance and low dry shrinkage.

5 、抗腐蚀性能好,尤其是抗海水腐蚀优于高抗硫波特兰水泥,抗腐蚀系数大于 1 。
   Good corrosion resistance, especially for seawater corro-sion is better than highly resistant Portland cement and the corro-sion resistance coefficient is larger than1.

三、用途 Usage
1 、冬季施工工程;
Construction in winter

2 、抢修工程;
Repair engineering

3 、喷锚支护工程;
Shot Crete and rock bolt support engineering

4 、水工海工工程;
Seawater engineering

5 、桥梁道路工程;
Bridge and highway engineering

6 、水泥制品、预制构件、高强预应力混凝土管桩。
Cement products and prefabricate component and high prestressing force conceret pipe pile

四、包装贮运:
  
袋装水泥每袋净重 50 ㎏,随机抽取 20 袋,总值量不得少于 1000 ㎏,其他包装形式由供需双方商定。在运输和贮存时,不得受潮混入染物,不得与其他水泥混杂贮存;贮存期为三个月,过期应重新测试合格后再使用。

IV. Packaging, storage and transport:
  
The cement is packed in bags with a net weight of 50 ㎏ each ,random sampling of 20 bags, the total weight is no less than 1000 ㎏ , and other forms of packaging are to be decided by the supply and demand parties. In transport and storage special attention should be paid to guard against dampness, agglomeration, and mixture of other types. The shelf life of the products is 3 months, of the time limit is exceeded, it should be rechecked to ensure that it is qualified before use.
