摘要

This study investigates the effect of steam curing on the early strength of mortars that include mineral admixtures. Instead of CEM I 42.5 R cement,0,10,20 and 30% of fly ash or 0,5,10 and 15% of silica fume was used in the mortars. In the composition of the mortars,the fine aggregate/ binder/water ratios were determined as,respectively,3/1/0.5 by mass. 40/40/160-mm prismatic specimens were cast and divided into two groups. The first group of specimens was cured in water at 20°C for 1,2,3 and 28 days. The second groups of specimens were exposed to 24-,48- and 72-h curing at procedure temperatures of 35,50,65,80 and 100°C. Following the curing,compressive strength of mortar specimens was determined. In this study,the accelerating curing temperature and time for the early strength of the mortars containing fly ash/silica fume were tried to determine according to compressive strength test results.
