Class N Natural Pozzolan

Class N Natural Pozzolan continues to be a valuable material for producing durable, sustainable, and high-performing concrete in modern construction.

Class N Natural Pozzolan is a category of pozzolanic materials defined by the American Society for Testing and Materials (ASTM) under ASTM C618, a standard that specifies the use of natural pozzolans and other supplementary cementitious materials in concrete. Pozzolans are materials that, when combined with lime and water, undergo a chemical reaction to form compounds that enhance the properties of concrete.

BENEFITS

Improved Durability: Reduces permeability and enhances resistance to sulfate attack and alkali-silica reaction (ASR) in concrete.
Sustainability: Can reduce the carbon footprint of concrete by partially replacing
Portland cement, a major source of CO₂ emissions.
Enhanced Workability: Often improves the flow and cohesion of fresh concrete.
Long-Term Strength Development: Promotes strength gain over time, particularly in aggressive environments.
