The unit weight of an AAC (Autoclaved Aerated Concrete) block can vary depending on its dimensions and specific composition. On average, the unit weight ranges from about 550 to 650 kg/m³ (30 to 34 pounds per cubic foot).
Full form of ACC block is Autoclaved aerated concrete. It is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. It is composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder.
In this article we know about what is unit weight of AAC Block and how we calculate, when we talk about weight of AAC Block, it is calculated by multiplying density (kg/m3) and volume (m3) of block. The regular size of AAC block is 600 mm × 200 mm × 100 mm and their volume is calculated 0.012 m3 and density 600 kg/m3, then weight of acc block is 0.012 m3 × 600 kg/m3 is equal to 7.2 Kg.
