Foam concrete, as a new type of energy-saving and environmentally friendly building material, has been extensively researched and developed by scholars both domestically and internationally, leading to its wide application in wall materials. Its advantages include low density, light weight, thermal insulation, soundproofing, and seismic resistance. However, it still has certain drawbacks, such as low strength, cracking, and water absorption. To further expand its application, further research is needed on foaming agents, mix ratios, process flows, and equipment. It can be used for retaining walls, construction of sports fields and track and field tracks, sandwich components, as composite wall panels, pipeline backfill, lean concrete fill layers, roof slopes, and support for storage tank bases. Nonetheless, it exhibits defects like low strength, cracking, and water absorption during use, and its performance needs further improvement.

Insulation and thermal protection

Due to the presence of numerous sealed tiny pores in foam concrete, it boasts excellent thermal properties, specifically superior insulation and heat retention capabilities, which are not found in conventional concrete. Foam concrete, typically with a density range of 300-1200 kg/m3, has a thermal conductivity of 0.08-0.3 W/(m·K) and a thermal resistance approximately 10-20 times that of ordinary concrete. Utilizing foam concrete as building wall and roof materials offers significant energy-saving benefits.

Insulation and fire-resistant

Foam concrete is a porous material, making it an excellent sound insulation material. It can be used as an insulation layer in building floors, soundproof panels on highways, and the top layers of underground structures. As an inorganic material, foam concrete is non-combustible, thus offering excellent fire resistance. Its use in buildings can enhance the fire safety performance of the structures.

Overall performance

The product can be cast in place for construction, closely integrated with the main project.

Low Resilience Damping

The porosity of foam concrete gives it a low modulus of elasticity, thereby enabling it to absorb and disperse impact loads effectively.

Excellent waterproofing properties

Ready-mixed foam concrete has a low water absorption rate, with relatively independent closed bubbles and good integrity, which endows it with certain waterproofing properties.

Durability

Has the same lifespan as the main project.

Processing convenience

Foam concrete can not only be produced into various products in the factory, but also can be constructed on-site, directly poured into roofs, floors, and walls.

Excellent environmental performance

Foam concrete requires cement and foaming agents, with most foaming agents being neutral and free from harmful substances like benzene and formaldehyde, thus avoiding environmental pollution and fire hazards.
