Portland Cement Type I/II Low Alkaline
Portland Cement Type I/II Low Alkaline (ASTM C150)
| Product Name | Portland Cement Type I/II Low Alkaline (ASTM C150) |
| Description | It is a cement type with medium sulfate resistance, with a tri-calcium aluminate (C3A) value of maximum 8%, which meets the requirements of ASTM C150 and AASHTO M 85. Standards, obtained by grinding the specially produced Low Alkaline Portland Cement clinker with set-regulating gypsum. It is resistant to alkali-aggregate reaction in concrete as it meets ASTM C150 Low Alkaline requirements. |
| Usage Areas | Due to its structure, it is a type of cement suitable for general use as TYPE I. It is mostly used for general construction purposes such as precast concrete products, reinforced concrete buildings. Since it also meets TYPE II requirements, it is suitable for use in applications where concrete will come into contact with the ground. It can be used in drainage structures that may be exposed to moderate sulfate attacks from groundwater, and in constructions such as sewers, bridges and pavements. |
| 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..
