✦ Synopsis
specimens at high compressive stress level and by acetone impregnation were compared with ASTM and Hg porosity with promising results. Good porosity/strength correlations were found and a previous strength/time mathematical model always verified for cement without fly-ash was adjusted with success, to establish limit strengths or strength reserves for infinite ages, related with potential compaction and durability. gal021 33
