SikaTard® R is a liquid admixture developed for the control of cement hydration. SikaTard® R retards/stabilises sand/cement masonry mortars and concrete mixes.
- Strong retardation/stabilising to enable brick/block laying to continue over long periods of time
- Delays the set of the mortar, however the retarding/stabilising effect declines once in place as moisture evaporates and migrates due to the suction of the brick/block enabling setting and curing to occur as normal
- Provides higher ultimate strengths
