Abstract: The paper discusses and analyzes main factors affecting the dry shrinkage deformation such as mortar strength, the ambient temperature, the relative humidity, the curing age and the height. The measures avoiding the cracking of autoclaved fly-ash aerated concrete masonry wall based on the experiment results is guiding to the engineering practice.
