HYDRATION STABILIZER FOR SHOTCRETE AND READY-MIX APPLICATIONS
SikaTard®-930 is an admixture for the control of cement hydration. SikaTard®-930 allows stabilization of concrete mixes for long periods without negatively influencing the 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.
