Cement sound barrier

Core materials: Commonly used ones include lightweight and high-strength perforated cement sound-absorbing boards and foamed cement composite boards. For example, in the ECP cement sound barrier, the core material is the foamed cement composite board, which has countless honeycomb-shaped micro-holes inside and can effectively absorb noise. Structural forms: It can adopt a single-layer structure, or be combined with metal materials, light-transmitting materials, etc. to form a composite structure. Some cement sound barriers adopt a three-layer composite structure. The surface layer is a high-density cement board, which is used to block noise; the middle layer is a foamed cement layer, which is responsible for absorbing noise; and the inner layer is a damping coating, which can suppress vibration. Features Environmental friendliness and easy installation: The raw materials are environmentally friendly and do not contain harmful substances such as formaldehyde and heavy metals. It is easy to install and maintain, and the construction and installation are not restricted by the climate. Superior performance: It is resistant to acid erosion, anti-aging, has strong weather resistance, good moisture (water) resistance, has good compressive strength and aesthetic plasticity, comes in various forms, and can be sprayed with various colors and patterns to meet the requirements of landscape decoration.
