Lightweight Concrete An Overview Sciencedirect Topics

The autoclaved aerated method is generally used in the production of AAC masonry blocks. This is because the aerated concrete, sometimes known as cellular concrete, produced from this method has a uniformly generated cellular structure of air voids in the range of 0.11 mm forming in the cement paste or mortars Mindess et al., 2003.
