AbstractPortland cement mortars made with various minerals as aggregates (1 part cement to 4 parts aggregate by volume) were cured in saturated steam at 150 C. The tensile strengths were compared with those attained by curing at 21 C. Among the aggregates used were the soda-lime (albite- anorthite) series of feldspars as well as microcline and anorthoclase. Similiar experiments were made with aggregates from some rocks of mixed mineralogical composition. It was found that the mineral composition of the aggregate influenced greatly the strength attained on autoclaving and to a lesser extent that attained at room temperature.
