Aerated Concrete

Aerated concrete is a construction material gaining popularity in single-family housing. It is produced by introducing air or gas into a plastic cement mixture, usually using aluminum powder or a foaming agent. This process creates pores or air cells, giving the material its name. Due to its high porosity, aerated concrete offers excellent thermal insulation properties.

Material Classification

Aerated concrete is categorized into classes ranging from 300 to 800.

• Higher numbers indicate denser and stronger material but with lower thermal insulation.
• Lower numbers provide better insulation but lower structural strength.

Advantages of Aerated Concrete

Lightweight, making construction easier and faster
Excellent thermal insulation due to high porosity
Easy to cut and shape, allowing flexibility in design
More affordable compared to other building materials

Disadvantages of Aerated Concrete

High water absorption, which can be problematic in some conditions
Low compression strength and brittleness, which may affect durability

Despite these drawbacks, aerated concrete meets structural and insulation requirements for single-family homes, where load-bearing demands are lower than in public or commercial buildings.

Key Properties of Aerated Concrete

• High porosity
• Good thermal insulation
• Lightweight structure
• Accelerates construction time
• Easy to process and shape
• Absorbs moisture
• Lower compression strength and higher fragility
