Batimix HWR WG7-L

Liquid, superplasticiser for shotcrete – Wet process application

Description

BATIMIX HWR WG7-L is a liquid 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-L 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-L 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

0.5% to 2.4% of the cementitious materials.

Available Packages

• 1 t IBC
• 200 kg metallic drum
• 20 kg metallic pail
• 4 kg metallic pail

Health and Safety

BATIMIX HWR WG7-L is not a hazardous material. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.
