WINFLOW-SL, a liquid type admixture based on PNS/Lignin system, improves the quality of concrete by reducing W/C ratio, and also gives good workability. And this air-entraining admixture provides concrete with extra protection by creating micro air bubbles that are ultrastable, small and closely spaced. This characteristic increases durability, quality and workability of concrete, and increases resistance from freeze-thaw cycle.
● USAGE
● DOSAGE
However, variations in job conditions and concrete materials, such as silica fume, may requires
dosages outside the recommended range.
