Polycarboxylate-based superplasticizer for concrete
BATIMIX HWR 1500 is a high-performance liquid high-range water-reducing (superplasticizer) admixture for concrete. It is based on synthetic polycarboxylate acid derivatives and on carefully selected chemicals.
BATIMIX HWR 1500 significantly improves concrete workability and allows an effective reduction in the free water content. It is a superior deflocculating product, with a highly marked capacity to disperse cement agglomerates and flocks normally found in a concrete mix. The adsorbed superplasticizer molecules at the cement-water interface induce repulsive forces due to steric hindrance between polymer layers. Thus specified concrete strength grades are achieved with significantly reduced cement content and/or increased workability.
Applications using BATIMIX HWR 1500 include all types of concrete castings such as plain, self-consolidating, reinforced, precast, read-mixed, lightweight, pumped, and shotcrete.
Concrete prepared with BATIMIX HWR 1500 is characterized by the following:
In the plastic state:
In the hardened state:
For normal superplasticizing effect, BATIMIX HWR 1500 should be used at dosage rates varying from 0.2% to 1.0% of the cementitious materials. Such addition rates increase up to 1.4% in case higher slump concrete is required.
BATIMIX HWR 1500 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.Reference:MK-PR-5496
