Construction
PCE
FEATURES
General Properties: High-performance anionic polymers with long side chains; typically clear to slightly hazy yellowish liquids.
Synergistic Role: PCEs stabilize air bubbles due to their surfactant-like structure. The defoamer must rapidly collapse these large bubbles while preserving the workability, flow, and slump retention provided by the PCE.
Performance Benefits:
Eliminates Harmful Voids: Removes large entrained air, increasing concrete density and compressive strength.
Maintains Workability: Does not interfere with the PCE's water-reducing and dispersing efficiency.
Improves Surface Finish: Prevents surface bug holes and honeycombing in architectural and precast concrete.
