Description
ZYLA® 640 water-reducing admixture is a proprietary formulation incorporating polycarboxylate and highly purified specialty organic chemicals. ZYLA® 640 promotes more complete hydration of Portland cement and has minimal 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® 640 is supplied as a light brown, low viscosity liquid, and is ready-to-use as received. ZYLA® 640 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).
Application areas
- ZYLA® 640 is suitable for normal weight and light weight concrete in ready-mix, precast and prestressed applications
Benefits
- No impact on concrete air content
- Better control of water reduction and setting times as compared to traditional lignin-based water reducers
- Synergistic performance of polycarboxylate-based mid-range and high-range water reducers, which includes water reduction and concrete strength and air control
- In the hardened state, improves the compressive and flexural strengths at all ages of concrete versus traditional lignin-based water reducers
Packaging
- 55 gallon drum
- 275 gallon tote
