Product type
Fly Ash Based PPC Cement is a type of blended cement that incorporates fly ash as a partial replacement for Portland cement. This innovative material is produced by mixing Portland cement with fly ash, which is a byproduct of coal combustion in power plants. The addition of fly ash enhances the durability and workability of the cement while reducing the overall carbon footprint of the cement production process. It is widely used in various construction applications due to its improved performance characteristics.
| Composition | Portland cement and fly ash |
| Typical fly ash content | 15% to 35% |
| Setting time | Initial set: 30 to 120 minutes; Final set: 180 to 300 minutes |
| Compressive strength | 20 to 50 MPa at 28 days |
| Water-cement ratio | 0.4 to 0.6 |
| Standard grades | PPC 33, PPC 43, PPC 53 |
When selecting Fly Ash Based PPC Cement, consider the specific application and environmental conditions. Important factors include the desired strength grade, the percentage of fly ash to be used, and any relevant certifications such as IS 1489 for PPC. Be sure to specify the required compressive strength and setting time based on project needs. Additionally, inquire about the supplier's quality control measures and availability of bulk quantities.
