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.
Improved bond between sprayed concrete and substrate and between subsequent concrete layers
Reduced evaporation of water the first hours after spraying
No external curing membrane necessary
Reduced water permeability for permanent sprayed concrete applications
Compatible with all types of cements
TamCem iBond can be used for all types of wet-mix sprayed concrete applications, and is especially suitable for sprayed concrete applications in windy/draughty environments and in hot climates.
