Which is NOT a characteristic of Autoclaved Aerated Concrete?

Autoclaved Aerated Concrete (AAC) is well-known for its distinctive properties, which include being lightweight, providing excellent thermal insulation, and having a high level of compressive strength.

Lightweight refers to AAC's reduced density compared to traditional concrete, making it easier to handle and transport. Its thermal insulation capability stems from the air pockets within the material, allowing it to maintain temperature control and improve energy efficiency in buildings. Additionally, AAC possesses commendable compressive strength, allowing it to support structures effectively while still being less dense.

However, high density is not characteristic of AAC. In fact, one of the key advantages of AAC is its lower density, which is achieved through the manufacturing process that incorporates air bubbles. This property distinguishes it from traditional concrete, which is typically much denser. Thus, the assertion that high density is a characteristic of Autoclaved Aerated Concrete is incorrect.
