Abstract: This paper introduces the development history of foam concrete as well as foaming processes for its preparation (including both physical and chemical foaming methods, foaming mechanisms of different foaming processes and foaming research progress). The effects of foam properties are analyzed, such as bubble structure, content and uniformity on the physical and chemical performances of foam concrete, including mechanical, thermal insulation and acoustic performances. The research modification and application progress of foam concrete at home and abroad are described, and its new environment-friendly and multi-functional applications are predicted to be the future development direction.
Keywords: foam concrete; foaming process; bubble structure; physical and chemical properties; modified application
