Abstract

An autoclave environment of 110°C and a steam pressure of 25 psi. was used to develop a rapid method of determining the expansive characteristics of some carbonate rocks. The current procedure for such determinations requires several weeks treatment of the aggregate sample in a lN NaOH solution at room conditions. Application of the autoclave method indicates that the rate of expansion is greatly increased but that the actual mechanism of expansion is not changed. Only those samples placed in an alkaline solution in the autoclave expanded. Control samples in distilled water showed negligible expansion. The expansion data obtained by the autoclave method is correlative with that obtained by standard procedures, but the test time required is considerably less. Therefore, this rapid autoclave method is suggested as a valid and applicable test in the study of carbonate aggregates.
