Set retarding admixture

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 to enable masonry laying to continue over long periods of time
  • Delays the set of the mortar, however the retarding effect declines once in place as moisture evaporates and migrates due to the suction of the masonry enabling setting and curing to occur as normal
  • Provides higher ultimate strengths
Usage
SikaTard® R allows the production of retarded/stabilised sand/cement masonry mortars.
SikaTard® R is mainly used for the following applications:
  • A wide range of applications where set retarding/stabilising is requested
  • In conjunction with Sika® Intraplast®-125 M to provide masonry mortars for laying brick/blocks manufactured from absorbent materials such as clay, sand-line and concrete.
