Set retarding/stabilising admixture 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. - 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 Sika® 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.

Usage SikaTard®-930 is can be used in a variety of materials including readymixed concrete and both wet and dry spray shotcrete, where cement hydration of the concrete mix is halted for a required amount of time. It is possible to retard/stabilise mixed concrete for a period of anything from hours to days. 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 Sika® Sigunit® is used as an accelerator. Thus hydration of the previously stabilised shotcrete will start immediately.
