Product type
Low Heat Portland Cement is a type of cement that generates less heat during the hydration process compared to ordinary Portland cement. It is formulated to have a lower content of tricalcium aluminate, which helps in reducing the heat of hydration. This makes it particularly suitable for large-scale concrete structures where temperature control is crucial to prevent cracking and ensure structural integrity.
| Chemical composition | Lower tricalcium aluminate content |
| Heat of hydration | Reduced compared to standard Portland cement |
| Typical strength | 25 to 50 MPa at 28 days |
| Setting time | Extended setting time compared to ordinary Portland cement |
| Standard sizes | Available in various bag sizes, typically 25 kg to 1 ton |
When selecting Low Heat Portland Cement, consider the specific heat requirements of your project and the potential for temperature-related issues. It is important to specify the desired strength grade, any relevant environmental conditions, and the quantity needed for your project. Additionally, inquire about certifications and compliance with local regulations to ensure quality and performance.
