When to add admixtures

In general, for optimum performance, admixtures should be added at the end of the batching process along with some of the mixing water, never directly onto dry materials. The timing of the addition affects the performance and so it is important that the admixture is always added at the same point in the batching process to ensure consistent performance.

Ready-mixed concrete suppliers optimise their batching sequence for the equipment they use.
