Foam concrete is an environmentally friendly and energy-efficient building material. It is produced by generating a foam from a foaming agent solution using a physical method, and then incorporating this foam into a cement-based slurry containing aggregates, admixtures, and water. The mixture is then cast and cured either naturally or through steam, resulting in a lightweight, porous concrete. Due to its unique properties, foam concrete is widely used in various construction applications such as building insulation, tunnel linings, highway backfilling, and lightweight structural components. Its future in the construction industry looks very promising.
One of the key features of foam concrete is its lightweight nature. The density of YT foam concrete typically ranges from 300 to 1800 kg/m³, with common grades between 300 and 1200 kg/m³. Recently, ultra-light versions with a density as low as 160 kg/m³ have also been developed and applied in construction. Because of its low density, using foam concrete in walls, floors, and other structural elements can reduce the overall weight of a building by approximately 25%, and in some cases up to 40%. This not only makes structures more efficient but also improves their load-bearing capacity when replacing traditional concrete.
Another significant advantage is its excellent thermal insulation properties. Thanks to the numerous closed pores within the material, foam concrete offers superior insulation compared to regular concrete. For densities ranging from 300 to 1200 kg/m³, the thermal conductivity is between 0.08 and 0.3 W/(m·K), which is about 10 to 20 times better than that of conventional concrete. This makes it ideal for use in walls and roofs, significantly improving energy efficiency.
In addition to thermal performance, foam concrete also provides good sound insulation and fire resistance. As a porous material, it effectively absorbs sound, making it suitable for use as a soundproofing layer in floors, highways, and underground buildings. Being an inorganic material, it is non-combustible and enhances the fire safety of buildings.
Foam concrete can be cast on-site, allowing it to integrate seamlessly with the main structure. It also has strong waterproof properties due to its low water absorption and the presence of independent, closed bubbles, which help maintain its integrity and prevent moisture penetration.
Moreover, foam concrete is known for its durability and environmental benefits. It reduces the carbon footprint of construction projects and contributes to sustainable development. With its versatility and performance, foam concrete is becoming an increasingly popular choice in modern construction practices.
