HIGH-PRESSURE STEAM CURING OF HIGH-SLAG CEMENT. II. STRENGTH OF CEMENT-SAND MIXES

The strength of dense high-slag cement-sand mixes autoclaved at 180lbf/in2, and of certain aerated mixes autoclaved at pressures ranging from 120 to 210 lbf/in2, has been determined. It was found that maximum strengths were developed in an autoclaving period of 5h at 180 lff/in2, and that longer periods, as well as higher autoclaving pressures, yielded lower strengths. The maximum strength values obtained for compacted 1:3(w/w) mixes were 425kg/cm2 in the absence of fine quartx, and 510 kg/cm2 in the presence of a suitable addition of fine quartz. The corresponding values for portland cement mixes were, respectively, 330 and 460 kg/cm2 for a heating period of 5h, and 360 and 505kg/cm2 for a period of 6h. /AUTHOR/
