CONCRETE AGGREGATE DURABILITY TESTS

Several procedures are studied in an attempt to develop a less time consuming substitute for the sodium sulfate soundness test. Considered were procedures using elastic fractionation, heavy media separation, autoclave degradation, freezing and thawing of aggregates, and others. One procedure, detrition value test, correlates fairly well with soundness test losses for aggregates from one area of the state where the soundness test is a controlling factor in aggregate processing. This procedure consists of the dynamic abrasion of water and aggregate in a 5 gallon bucket on a paint shaker. A test method was developed and an alternate specification to the soundness test requirement written for control of aggregate quality. The specification is currently limited to aggregates from the Santa Clara River area near Ventura.
