Liquid water-repellent for concrete, mortars and grouts
BATIMIX IWR 421 is a liquid, integral water-repellent admixture used in all types of concrete mixes to reduce absorptivity and water penetration from the surrounding environment. It is blended with plasticizing polymers for improved workability.
BATIMIX IWR 421 significantly decreases the water permeability of concrete. It creates a network of insoluble water-resistant material within the pores of the cement matrix. The addition of this admixture leads to the formation of an effective internal barrier. This prevents water transmission throughout the concrete. The mixing-water demand for the same workability decreases as the plasticizing polymers existing in BATIMIX IWR 421, ensure denser and more durable concrete.
Applications using this product include all types of plain and reinforced concrete castings, such as precast, ready-mixed, lightweight, pumped, and shotcrete.
Concrete prepared with BATIMIX IWR 421 is characterized by the following:
In the plastic state:
In the hardened state:
0.2% to 1.2% of the cement weight
Liquid brown
BATIMIX IWR 421 is not considered a hazardous product. 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.
