TamCem iBond


TamCem iBond is an aqueous, solvent-free, chloride-free internal curing agent designed for wet-mix sprayed concrete to improve the bond between the sprayed concrete layers and/or to the substrate, and to reduce rapid evaporation of water from the sprayed concrete, typically in permanent sprayed concrete tunnel linings exposed to high levels of ventilation draught, or low relative humidity.

TamCem iBond meets the EN 934-5 compliance requirements for bond-improving admixtures.

Compatible with all types of cement.

Key specification

  • Concrete curing agent for wet-mix sprayed concrete
