Retarders are concrete admixtures designed to slow down the setting time of concrete. They are particularly useful in situations where there is a need to extend the working time of the concrete or when delays in placement and finishing are expected. Retarders offer flexibility in concrete placement, especially in situations where the construction schedule may be affected by logistical challenges or when a deliberate delay in setting time is needed.
