ABSTRACT:
A process for adding water to a concrete mix wherein, after addition of an initial quantity of water to bring a particular concrete mix to or close to a so-called zero consistency, the set point consistency is reached by the one-shot addition of the balance of the water determined from stored empirical and interpolated data based upon measuring consistency and water addition values. The method has the advantage that the establishment of a zero value consistency by the addition of water to the dry mix or a mix of unknown moisture content permits the consistency measurement at this point to be easily carried out by indirect electrical techniques.
