Zyla® 630

Zyla® 630 water-reducing admixture is a proprietary formulation incorporating highly purified specialty organic chemicals. Zyla® 630 promotes more complete hydration of Portland cement and has no effect on concrete air entrainment. The Zyla product line of water reducers is specially formulated to have a synergistic effect with polycarboxylate-based mid-range and high-range water reducers that improve flat-work finishability. This product contains no intentionally added chloride and as such is essentially chloride free. It is manufactured under rigid controls that provide uniform, predictable performance. Zyla® 630 is supplied as a light brown, low viscosity liquid, and is ready-to-use as received. One gallon weighs approximately 9.1 lbs (1.1 kg/L).
