In this study, the use of alkali activated slag (AAS) in place of usual cementitious materials in the production of autoclave aerated concrete (AAC) was studied. This substitution altered autoclave curing stage by steam curing in MC production process. In this way, after mixing of AAS paste with aluminum powder. enough time was given to the mixture. The resultant green body was then cured at 70, 78 and 87 degrees C. To achieve the best results, microscopic pore structure, compressive strength of the body and mini-slump of initial paste were studied. The results approved that AAC can be produced without autoclave by using AAS. (C) 2011 Elsevier Ltd. All rights reserved.
