Abstract
The objective of the present study is to evaluate a practical approach for enhancing the compressive strength and minimizing deforming of aerated concrete. Test results measured in the aerated concrete mixes that were produced using 40% ground granulated blast-furnace slag (GGBS) as a replacement of cement and cured under different conditions (i.e., high temperatures of $40^{\circ}C$ and $60^{\circ}C$ for 10 hrs or 15 hrs) were compared with those obtained from the specimens cured under room temperature. No deforming was observed in the mixes with 40% GGBS. The compressive strength of the prepared aerated concrete cured under high temperature was higher than that of the concrete cured at room temperature, even at the lower ranges of the apparent dry density. However, the curing time is needed to be controlled as not exceeding 10 hrs at the temperature of $60^{\circ}C$ to prevent the decrease in the compressive strength due to foam mergences.
