Thermal insulation: thermal conductivity is 0.06-0.28W / (M.K), and thermal resistance is about 10-20 times that of ordinary concrete.
Lightweight: The dry bulk density is 300-1600KG / M3, which is equivalent to about 1/5 to 1/8 of ordinary cement concrete, which can reduce the overall load of the building.
Integrity: It can be poured on-site for construction, and it is closely integrated with the main project, without the need for borders and ventilation pipes.
Low elastic shock absorption: The porosity of foamed cement makes it have a low elastic modulus, so that it has a good absorption and dispersion effect on impact loads.
Sound insulation: Foamed cement contains a large number of independent air bubbles and is evenly distributed. The sound absorption capacity is 0.09-0.19%, which is 5 times that of ordinary concrete, and has effective sound insulation.
Compression resistance: Compressive strength is 0.6-25.0MPA.
Water resistance: In-situ foamed cement has a small water absorption, relatively independent closed air bubbles and good integrity, which makes it have a certain waterproof performance.
Durability: Same as the life of the main project.
Simple construction: Just use a cement foaming machine to achieve automatic operation, and achieve long-distance transportation with a vertical height of 200 meters. The workload is 150-300M3 / working day.
Production processability: Not only can foam cement be produced in the factory into a variety of products, but also can be constructed on-site, directly cast into roofs, floors and walls, and can be sawed, planed, nailed, drilled, etc. machining.
Environmental protection: The raw materials required for foaming cement are cement and foaming agent. The foaming agent is neutral and does not contain harmful substances such as benzene and formaldehyde, which avoids environmental pollution and hidden fire hazards.
Fire resistance: Because the main raw material of foamed cement is cement, cement is an inorganic material that is completely fireproof.
History development
Thermal insulation materials and products are an important factor influencing building energy efficiency. The development and application of building insulation materials has received increasing attention from countries around the world. After the 1970s, foreign countries generally paid attention to the production of thermal insulation materials and their application in buildings, and strived to significantly reduce energy consumption, thereby reducing environmental pollution and the greenhouse effect. Foreign insulation materials industry has a long history, the majority of insulation materials for building energy saving, and new types of insulation materials are constantly emerging.
