Master Pozzolith

Whatsapp Order

Master Pozzolith is a high-performance concrete admixture designed to improve the workability, strength, and durability of concrete. It acts as a water-reducing agent and plasticizer, enabling reduced water content while maintaining slump and flow characteristics. This results in enhanced compressive strength, reduced permeability, and improved resistance to weathering and chemical attack. Master Pozzolith is widely used in ready-mix concrete, precast elements, and structural applications to optimize concrete performance and longevity.

Master Pozzolith

Primary Uses

Water Reduction and Workability Enhancement

Reduces water content in concrete mixes without compromising workability, allowing for stronger concrete.
Improves slump retention and flow for easier placement and finishing.

Strength Improvement

Increases early and ultimate compressive strength of concrete.
Enhances cement hydration efficiency.

Durability Enhancement

Reduces permeability, improving resistance to chloride ingress, sulfate attack, and freeze-thaw cycles.
Enhances concrete’s resistance to cracking and surface scaling.

Secondary Uses

Precast Concrete

Used to improve surface finish and reduce curing time in precast concrete products.

Shotcrete Applications

Improves pumpability and cohesion in sprayed concrete for tunnels and retaining walls.

Grouting

Enhances flow and strength in grout mixes used for anchoring and repairs.
