Correcting for Aggregate Moisture| Concrete Construction

Fortunately, the aggregate moisture correction is routinely applied by the concrete producer at the time of batching, estimating the moisture condition of the aggregates and changing to the batch weights as required. The calculations usually are done automatically in the batching computer based on input values for aggregate moisture and absorption.
