Abstract
Foamed concrete with its super low density of between 150Â kg/m3 and 300Â kg/m3 was prepared by means of chemically foaming and so called mixing and foaming process in laboratory. Conventional Portland cement was selected as the main binding material instead of rapid hardening special cement such as sulfoaluminate cement. Chemical and physical admixtures were properly introduced for the regulation of the rheological property and hardening speed of the fresh cement mixture slurry as well as the physical properties of the hardened foamed concrete. The resultant foamed concrete with its curing age of 28Â d thus obtained presents its compressive strength between 0.33Â MPa and 1.1Â MPa, water absorption between 6.6% and 8.3% and thermal conductivity between 0.05Â W/mK and 0.07Â W/mK.
