These are hydraulic binders (referred to as high strength double-fast cement) with super-high strength, fast setting and rapid hardening properties, made from active mixed materials such as fast setting rapid hardening high belite sul aluminate cement clinker, moderate amount of gypsum (or industrial by-product gypsum), slag, prescribed mixing amount of fly ash and steel slag with fine grinding.

1. Fast setting, Rapid hardening, high strength; 4h compressive strength can reach 15Mpa, 102Mpa after 28d, suitable to make the high strength products.
2. Micro expansion, low dry shrinkage, the length change is very small. Dry shrinkage rate is just 1/8 of Portland cement.3. Have very good anti-corrosion property in sulfate, chloride, magnesium salt and seawater. Corrosion resistance coefficient >1.4. High impermeability, permeation height is 1/5 of Portland cement.5. High frozen resistance property, can get the strength of critical intensity of cold in 2h~3h.6. Low hydration heat release7. value is under 10.0 for GRC products.8. High whiteness value, the Hunter whiteness is above 75.9. Re-alkali resistant performance is good10. Can be mixed with Portland cement in a proper ratio, can greatly reduce the shrinkage of Portland cement, reduce the cracks.1. GRC

Q: Can I speak with a Korean Speaker?A: Of course, we have Korean employee.Q: Are you a factory?A: Yes, we are a factory, but not just a factory, as we have sales team, our own offices, professionals, masters and doctors, and they all can help the buyers and cooperative partners to decide which products are the best choices for them, and all your requirements and inquires will be replied in time.Q: Could you send me all your catalogs and price lists?A: As we have about 56 products, please inform us the products, size and packages you interested in, so that we are capable to offer the price lists to you for your reference .Q: Could you send me some samples?A: Of course we're capable of sending you some free samples for your evaluation by air for speed increases. And it's free for the delivery charge while the weights under 5 kg, but we are afraid you should pay for the delivery charge if the total weight exceeds 5 kg.
