at elevated temperature, but very few studies compare in- depth the activation of GGBS paste with different curing conditions. This paper emphasizes the effect of curing method on the compressive strength development of alkali activated blast furnace slag paste.

During the field application of lime treatment, the curing conditions are far from been controlled especially in arid and semi-arid climates. This study aims at investigating the effect of different curing environments on the UCS of lime-treated expansive clays.

different mix designs and subjecting them to six different curing conditions. In order to investigate the influence of curing conditions, on the compressive strength

These different opinions results into this study, which aim at investigating the effects of different curing methods on the strength of concrete. Laboratory test was employed for this study. Normal concretes were prepared using specified mix ratio of 1:2:4 and 1:3:6.

In this study, compressive strength values were measured at different curing times (3, 7, 14, 28, and 56 days). The value of the room-high temperature and standard curing (0RHSC) series is higher than that of the high temperature and standard curing (0HSC) series.

This study considered the effect of different methods of curing on density and compressive strength of concrete. Concrete cube specimens of mix 1:2:4 were prepared with water-cement ratio of 0.65. The cubes were cured using six methods (air curing, water-submerged curing, spray curing, polythene curing, moist sand curing and

different curing temperatures at 20±2°C, 35±2°C, and 50±2°C. As for the effect of curing relative humidity, the specimens were placed in a controlled temperature chamber at 20±2°C. At three days after mixing, the specimens were removed from their moulds and cured in five different environmental conditions until the required age was reached.
