二、特性
有快硬水泥的早強特性，又有堿低，膨脹率低，穩(wěn)定期短，干縮率小的優(yōu)點。與玻璃纖維復合強度保留率高，使用壽命長，是 GRC 制品的專用產(chǎn)品。
Characteristic
It has early strength characteristics of fast hard cement and low alkalinity, low expansivity and short steady period as well as little dry shrinkage. And it has also high compound strength with fiberglass and it has a longer service life and is a special product for GRC product.
三、用途
用于生產(chǎn)輕質(zhì)內(nèi)外復合墻板，波瓦、網(wǎng)架板、通風道、歐式浮雕各種構(gòu)件，建筑小品等 GRC 制品。
Usage
Used in production of GRC product such as light endosaro and outer compound wall plate, ripple tile, net frame plate, ventilation stack and various components of European basso-relievo and small buildings.
四、包裝貯運
袋裝水泥每袋凈重 5 0 ㎏，隨機抽取 20 袋，總質(zhì)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，不得受潮和混入雜物，不得與其他水泥混雜貯存。貯存期為三個月，過期應(yīng)重新測試合格后再使用。
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 dem and parties. In transport and storage special attention should be pais 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.
五、注意事項
攪和好的物料一定要控制在 20min 內(nèi)用完。拌和料失去流動性后，不得第二次加水拌合再使用。水泥制成品應(yīng)在 2h 內(nèi)即灑水養(yǎng)護，養(yǎng)護期不少于三天。冬季施工時，要注意防寒措施，必要時加適量亞硝酸納，要進行蓄熱養(yǎng)護。
Cautions
Mixed cements must be used up in 1.5h. After loss of fluidity of the mixed cements, it is not permitted to add water for the second time to use. As to the finished cement products. sp-rinkling to maintain after 2h, and the maintenance period is no less than 3 days. When constructing in winter, measures to guard against cold should be taken and add proper nitrite if necessary and it is necessary to store warmth to maintain
