Pozzolanic Portland Cement (Special)NextEraGlobalCommerce proudly offers Pozzolanic Portland Cement in compliance with Iranian National Standard No. 3432. Pozzolanic cements are classified into two categories based on the percentage of added pozzolan material:
Pozzolanic Portland Cement (P.P.): Contains a minimum of 5% and a maximum of 15% pozzolan by weight.
Special Pozzolanic Portland Cement (P.P.W.): Contains a minimum of 15% and a maximum of 40% pozzolan by weight.
Key Features and Benefits of Pozzolanic Portland Cement (Special) for Construction and Dam Projects:
The use of Pozzolanic Portland Cement significantly improves various properties of concrete, making it ideal for demanding applications, especially in foundation work and dam construction. Below are the key advantages:
Improved Concrete Durability: The high Blaine fineness of Pozzolanic Portland Cement adjusts the cement reaction process, increases the specific gravity of the concrete, and enhances its final strength.
Reduced Permeability: The Pozzolanic reaction reduces the formation of free lime in the concrete, leading to lower porosity. This reduces permeability, preventing issues such as efflorescence and improving long-term durability.
Enhanced Resistance to Aggressive Environments: The use of pozzolanic materials increases the concrete's resistance to sulfate and chloride corrosion, protecting the reinforcement bars and concrete from aggressive environmental factors.
Low Heat of Hydration: The lower heat of hydration makes this cement ideal for mass concrete pours, helping control temperature fluctuations during the curing process.
Better Workability and Reduced Shrinkage: The increased adhesion of the mix improves workability, reduces the bleeding of concrete, and prevents issues like shrinkage, cracking, and expansion.
Sustainability: Pozzolanic cements contribute to the sustainability of construction by utilizing industrial by-products and improving concrete's resistance to environmental factors.
Applications of Pozzolanic Portland Cement (Special):
Dam Construction: Ideal for concrete used in dam foundations, providing long-lasting performance in wet conditions and sulfate-rich environments.
Building Foundations: Suitable for foundation work in areas with aggressive soils and environments.
Structural Concrete: Excellent for use in large-scale concrete projects, including bridges, roads, and paving.
Durable Concrete Structures: Perfect for concrete exposed to harsh weather and chemical attacks, enhancing the longevity of concrete structures.
