二、性能 Performance

1 、早強、高強:一天抗壓強度達天 3 0 ~ 50MPa ,三天達到 50 ~ 70MPa ,隨著養(yǎng)護期齡增長強度不斷增長。
   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 、高抗凍性能:在 0 ~ 10 ℃ 低溫使用,早期強度是波特蘭水泥的 5 ~ 6 倍; 0 ~ 20 ℃ 加少量外加劑, 3d ~ 7d 強度可達到設計標號的 70 ~ 80% ,凍融循環(huán) 300 次強度損失不明顯。
   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?jié)B性:水泥石結構致密,混凝土抗?jié)B性是同標號硅酸鹽水泥的 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,干縮率低。
   Good carbonization resistance and low dry shrinkage.

5 、抗腐蝕性能好,尤其是抗海水腐蝕優(yōu)于高抗硫波特蘭水泥,抗腐蝕系數(shù)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 、搶修工程;
Repair engineering

3 、噴錨支護工程;
Shot Crete and rock bolt support engineering

4 、水工海工工程;
Seawater engineering

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

6 、水泥制品、預制構件、高強預應力混凝土管樁。
Cement products and prefabricate component and high prestressing force conceret pipe pile

四、包裝貯運:
  
袋裝水泥每袋凈重 50 ㎏,隨機抽取 20 袋,總值量不得少于 1000 ㎏,其他包裝形式由供需雙方商定。在運輸和貯存時,不得受潮混入染物,不得與其他水泥混雜貯存;貯存期為三個月,過期應重新測試合格后再使用。

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.
