Abstract

This study was carried out to investigate the effect of steam curing condition on the early and later age strength of mortar, which was added various dosages of Calcium Nitrite Based accelerator, the study was performed on the specimens which subjected to the three different pre-curing time and exposed to the two different keeping curing times at the 45C° steam curing temperature. High early strength cement was used in this research experiment. From the obtained result, it was observed, that the early (8, hour) strength of specimens exposed to the long keeping curing time (4.5, hour) is higher than the strength of specimens subjected to the short keeping curing time, (3hours). Adversely, it is obtained that by increasing the ages of specimens, the strength gain goes up for the specimens exposed to short keeping curing time (3,hour), compared to the strength of the specimens exposed to longer keeping curing time (4.5, hour). Moreover, the obtained result indicates that the higher early and the later ages strength of specimens was observed from the specimens which accompanied to the pre-curing cycle 90 minutes, compared to the strength of specimens, exposed to pre-curing cycle 30 and 150 minutes. For all cases the result showed that, by increasing the dosage of the accelerator admixture the strength increased at the early and later ages.
