Batimix HWR WG7-P

Powder, superplasticiser for shotcrete - Wet process application

Description

BATIMIX HWR WG7-P is a powder high-range water-reducing (superplasticizer) admixture for shotcrete. It is based on high-grade naphthalene-sulfonate materials, which are blended with selected chemicals to accelerate concrete setting. It does not contain calcium chloride or other potentially corrosive ingredients.

Main Purpose

BATIMIX HWR WG7-P is designed to significantly improve the workability of shotcrete and/or to allow a reduction in the free water content. It functions by electrostatic repulsion, which results in a powerful dispersion of the fine cementitious particles in the concrete mix. The deflocculation allows specified strength grades to be achieved at reduced cement content and/or increased workability.

Features

Shotcrete prepared with BATIMIX HWR WG7-P is characterized by the following:

In the plastic state:

• Higher flowability without adding extra water
• Reduced water content up to 40% with minimum secondary effects
• Enhanced homogeneity, cohesion, and ability to pump the shotcrete mix
• Accelerated setting, especially suitable for shotcrete applications and cold climates

In the hardened state:

• Increased strengths - compressive, flexural, and bonding
• Reduced shrinkage, creep, water permeability, and cracking
• Enhanced durability and better surface appearance of the shotcrete

Dosage

0.2% to 1.2% of the cementitious materials.
