SikaTard® R

SikaTard® R is a liquid admixture developed for the control of cement hydration. SikaTard® R retards/stabilises sand/cement masonry mortars and concrete mixes.

USES

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 Sikanol® 118 to provide masonry mortars for laying brick/blocks manufactured from absorbent materials such as clay, sand-line and concrete.

CHARACTERISTICS & ADVANTAGES

SikaTard® R retards/stabilises the hydration of the cement.

  • 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

SikaTard® 930

SikaTard® 930 is an admixture in liquid form developed for the control of cement hydration. SikaTard® 930 stabilises concrete mixes without setting for extended periods and without negatively influencing their quality.

USES

SikaTard® 930 is mainly used in wet and dry spray shotcrete where cement hydration of the concrete mix is prevented until it is required. It is therefore possible to retard/stabilise mixed concrete for hours or even days.


SikaTard® 930 is mainly used for the following applications:

  • A wide range of applications where set retarding/stabilising is requested
  • Tunnelling work

CHARACTERISTICS & ADVANTAGES

SikaTard® 930 blocks cement hydration. This is in contrast to other stabilisers or retarders, which only retard hydration of the cement.

  • The effect of SikaTard® 930 may be immediately stopped when Sigunit® is used as an accelerator. Thus hydration of the previously stabilised shotcrete, will start immediately.
  • SikaTard® 930 does not contain chlorides or any other steel corrosion promoting materials. It can therefore be used in steel reinforced concrete construction without restriction.
