CEMENT CONTENT OF FRESH CONCRETE

A test method for determining the cement content of fresh concrete was developed for both laboratory and field use. Using hydrochloric acid to keep a concrete mixture constantly neutralized, the cement content can be determined to within about 1/4 sack per cubic yard. Field tests indicate the method is most useful in evaluating the performance of a concrete mixer. Relative cement contents of various portions of a batch can be determined in about one hour. Adjustments to aggregate and/or cement feed can then be made as needed to improve mixing uniformity.
