Introducing VCAS - Vitrified Calcium
Alumino-Silicate from Vitro Minerals

VCAS pozzolans are new, custom engineered high performance supplementary cementing materials for use in white Portland cement, mortars and concrete products. VCAS is free of iron, manganese and other undesirable color-inducing impurities, making them ideally suited for all applications using white cement, as well as pigmented concrete. VCAS contains no crystalline silica and is very cost-effective, especially compared to those using metakaolin as a pozzolan.

Benefits of VCAS include:

Fresh Concrete

• Improved workability
• Reduction in water requirements
• Ease of dispersibility
• Reduction in super plasticizer
• Reduction in aggregate segregation

Hardened Concrete

• Increases compressive strength
• Decreased permeability
• Increased durability
• Added-in value
• Mix-color neutrality and brightness
• Improved retention of molded detail
• Sustainability
