Product type
Portland Pozzolana Cement (PPC) is a type of blended cement that incorporates pozzolanic materials, which are siliceous or siliceous-aluminous materials that, when mixed with lime, form compounds that have cementitious properties. This cement is produced by grinding clinker with pozzolanic materials such as fly ash, volcanic ash, or silica fume. PPC is known for its durability, workability, and resistance to chemical attacks, making it suitable for various construction applications.
| Compressive strength | Typically 33 MPa to 53 MPa at 28 days |
| Setting time | Initial setting time of 30 to 60 minutes; final setting time of 600 minutes |
| Chemical composition | Contains a minimum of 15% and a maximum of 35% pozzolanic material |
| Water-cement ratio | Typically ranges from 0.4 to 0.6 |
| Standard grades | Available in grades like 33, 43, and 53 |
When selecting Portland Pozzolana Cement, consider the specific application requirements, such as the desired compressive strength and setting time. It is important to specify the grade of cement needed based on the structural demands of the project. Additionally, inquire about the pozzolanic material content and ensure compliance with relevant standards or certifications. Quantities should be estimated based on project size and scope to avoid delays.
