CEM I 52.5 N Portland Cement
CEM I 52.5 N Portland Cement (TSE EN 197-1)
| Product Name | CEM I 52,5 N Portland Cement (TSE EN 197-1) |
| Description | It is pure Portland cement with normal early strength and high final strength, obtained by grinding Portland Cement clinker with set-regulating gypsum in accordance with EN-197-1 standards. |
| Usage Areas | CEM I 52.5 N cement is widely used in a wide variety of applications. It is used in concrete production in the most difficult reinforced and non-reinforced structures such as bridges, tunnels and viaducts. CEM I 52.5 N type cement, which has a high strength class, is used in the construction of difficult buildings and structures that require rapid removal of molds due to technology and business dynamics. Although not limited to these, it is suitable for use in ready mixed concrete plants, high strength precast casting applications, shotcrete, grout concrete, joint, mortar, plaster and screed. |
| Sales Method | Bags between 25-50 kg
1.5 tons of slingbags Stretch hood with a capacity of 1.5-1.75-2 tons without pallet 1,5 ton bigbag Bulk *Can be supplied with a maximum of 2 ppm water-soluble chromium content in accordance with customer demand and legal regulations. |
| Conditions of Use | After pouring, appropriate curing and protection processes should be applied on the exposed surfaces of the concrete for at least 7 days.
Freshly poured concrete should be protected against the risk of freezing in cold weather. Concrete should be protected against cracking and thermal risks, as the loss of water in the concrete by evaporation will increase in hot weather and mass concrete casting applications. Due to the nature of the raw materials used in clinker production, slight color differences may occur. Our company is not responsible for problems arising from workmanship errors. |
| Storage | Contact of cement with air and moisture can cause hydration and change its properties. Therefore, in order to provide the recommended shelf life;
• Bulk cements should be stored in metal or reinforced concrete silos in a way that they will not come into contact with air and moisture. • Bag cements should be protected from humid environments. Bags should not be in direct contact with the ground, but should be stacked on pallets or timber. • It should be covered with a roof or cover so that it does not come into contact with direct sunlight. • Stacking instructions and shelf life under appropriate conditions are available on the bag.
