二、性能 Performance

1 、早強(qiáng)、高強(qiáng):一天抗壓強(qiáng)度達(dá)天 3 0 ~ 50MPa ,三天達(dá)到 50 ~ 70MPa ,隨著養(yǎng)護(hù)期齡增長(zhǎng)強(qiáng)度不斷增長(zhǎng)。
   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(qiáng)度是波特蘭水泥的 5 ~ 6 倍; 0 ~ 20 ℃ 加少量外加劑, 3d ~ 7d 強(qiáng)度可達(dá)到設(shè)計(jì)標(biāo)號(hào)的 70 ~ 80% ,凍融循環(huán) 300 次強(qiáng)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(jié)構(gòu)致密,混凝土抗?jié)B性是同標(biāo)號(hào)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(hù)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(yù)制構(gòu)件、高強(qiáng)預(yù)應(yīng)力混凝土管樁。
Cement products and prefabricate component and high prestressing force conceret pipe pile

四、包裝貯運(yùn):
  
袋裝水泥每袋凈重 50 ㎏,隨機(jī)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(yùn)輸和貯存時(shí),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(gè)月,過期應(yīng)重新測(cè)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.
