Foam concrete panel

Types of Foam Concrete Panel

Foam concrete panels, also known as foam concrete or cellular concrete panels, are building materials made from cement, water, foam agent, and aggregates. These components produce lightweight concrete with air pockets. Foam concrete panels come in different types based on their application, composition, and production methods. Here are some common types:

• Based on Composition and Construction Method

  Load-Bearing Panels: These panels are reinforced with steel mesh or fibers, enabling them to bear loads. They are used as structural components in buildings like foundations and walls. Non-Load Bearing Panels: These panels are not reinforced and are used to fill in or insulate walls. They are suitable for partitions and infill walls. Insulated Panels: These panels have a core of foam plastic insulation, such as polystyrene or polyurethane, which is sandwiched between two layers of concrete. They provide excellent thermal insulation and structural integrity.

• Based on Density

  Lightweight Foam Concrete: This type has a density of 300-1600 kg/m3. It is used for applications like void filling, lightweight blocks, and insulation. Medium Density Foam Concrete: This type has a density of 1600-2000 kg/m3. It is used for applications like structural walls and floors. High-Density Foam Concrete: This type has a density of 2000-2400 kg/m3. It is used for applications like heavy traffic areas and structural components that require high strength.

• Based on Application

  Structural Panels: These panels are made with a higher density of concrete and are reinforced with steel fibers or mesh. They can be used in load-bearing applications like walls, foundations, and floors. Insulating Panels: These panels have a core of foam plastic insulation, such as expanded polystyrene (EPS) or polyurethane foam, sandwiched between two layers of concrete. They provide excellent thermal insulation and are used in energy-efficient buildings. Precast Panels: These panels are cast in molds and cured before being transported to the construction site. They offer high precision and speed in construction. Cast-In-Situ Panels: These panels are cast on-site using removable wooden or metal forms. This method requires skilled labor but is cost-effective for large projects.
