The foaming agent for concrete form a foam with a certain tension and then mixing the foam and cement slurry at the same time. During the mixing process, the cement will continue to expand. When the expansion effect reaches the preset ratio, foamed cement can be formed.
The foaming agent for concrete are divided into two types: physical foaming and chemical foaming. In physical foaming, the foaming agent is pressurized by an air compressor (ie foaming machine) to form a foam with a certain tension, and then the foam is combined with the cement When the slurry is stirred at the same time. The cement will continue to expand during the mixing process, and foamed cement can be formed when the expansion effect reaches the preset ratio. Chemical foaming refers to adding a foaming agent (liquid/powdered solid) to the cement slurry for stirring, a chemical reaction occurs and gas is released to continuously expand the volume of the cement, and the expansion effect reaches the preset state of the formula to form foamed cement.
The performance of foaming agent for concrete
Strong thermal insulation
Because foamed cement contains a large number of closed pores. It has good thermal performance and good thermal insulation performance. The thermal conductivity of foamed cement with a density grade of 150-200kg/m³ can be controlled within 0.04~0.065w /(m·K).
Low density and lightweight
The density of foaming agent for concrete is small, and the density grade is generally 200~400kg/m3. The density grade of commonly used foamed cement is 200~300 kg/m3. In recent years, ultra-light foamed cement with a density of 150~180kg/m3 is also It has been applied in construction engineering.
Soundproof and fireproof
The foaming agent for concrete are a porous material, so it is also a good sound insulation material. It can be used as a sound insulation layer on floors of buildings, sound insulation boards of highways, and top floors of underground buildings. foaming agent for concrete an inorganic material and will not burn at all in a fire, so it has good fire resistance. When used on buildings, it can improve the fire resistance of buildings.
Water and frost resistance
The board has a high closed cell rate, which prevents moisture from entering, and achieves the effect of water resistance and frost resistance.
It is used for external wall insulation, using ordinary Portland cement foam board, which is the same quality and material as the base wall, and the project life is equal to the building life.
The raw materials required for foamed cement are cement and foaming agents. Most of the foaming agents are close to neutral and do not contain harmful substances such as benzene and formaldehyde, which avoids environmental pollution and fire-fighting hazards.
Only need to use cement foaming machine can realize automatic operation, can be pumped to realize long-distance transportation with a vertical height of 200 meters, and the workload is 150-300 cubic meters/working day.
Convenient production and processing
Foamed cement can not only be produced into a variety of products in the factory but also can be constructed on-site and poured directly into roofs, floors, and walls.
