Autoclaved aerated concrete (AAC) has low density, suitable compressive strength, and excellent thermal and sound insulation capacity for building non-bearing walls. However, porous AAC blocks usually have low flexural strength and thus are prone to cracking during service life. Herein, bamboo cellulose nanofibers (BCNF) were …

Autoclaved aerated concrete belongs to the category of lightweight concretes, with a density ρ usually ranging between 250 and 650 kg/m 3 [39], [41], [42], [43]. Its lightness directly derives from the microstructure of the material, which is characterized by a high total porosity, up to 85% of the hardened phase by volume [39], …

Under high-pressure steam conditions for curing, the gel-type calcium silicate hydrates (CSH) will become crystalline tobermorite, which then enhances the material's mechanical strength. The resulting material is called autoclaved aerated concrete (AAC), autoclaved lightweight concrete, or autoclaved cellular concrete.

Autoclaved aerated concrete is quite different from dense concrete (ie: "normal concrete") in both the way it is produced and in the composition of the final product. Dense concrete is typically a mixture of cement and water, often with slag or PFA, and fine and coarse aggregate. It gains strength as the cement hydrates, reaching 50% of its ...
