Concentrated superplasticizer for concrete with set acceleration
BATIMIX HWR 1300-A is a liquid cooncentrated high-range water-reducing (superplasticizer) admixture with enhanced properties for concrete. It is based on high-grade naphthalene-sulfonate materials blended with selected chemicals to accelerate setting. It does not contain calcium chloride or other potentially corrosive ingredients.
BATIMIX HWR 1300-A is designed to improve concrete workability and/or allow an effective reduction in the free water content. This product is a highly powerful dispersant, which functions by electrostatic repulsion, breaking-up agglomerates in the concrete mix. It allows for specified concrete strength grades to be achieved, with significantly reduced cement content and/or increased workability. It is particularly used in cold climates to decrease concrete setting times. It allows for the speeding-up of finishing operations and removal of formworks.
Applications using BATIMIX HWR 1300-A include all types of concrete castings, such as plain, reinforced, precast, ready-mixed, lightweight, pumped, and shotcrete.
Concrete prepared with BATIMIX HWR 1300-A 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 concrete mix
• Accelerated setting, especially suitable for use in 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 concrete

BATIMIX HWR 1300-A 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.
