There are still a lot of coal combustion products waiting for utilization in the Czech Republic. One of suitable building materials is fly ash aerated concrete. It is as a modern material combining high use value with environmental aspects of its production. Autoclaved aerated concrete is also one of the ways to use besides fly ashes from pulverized boilers fluidized bed combustion ashes. Significant advantage of the utilization of these CCPs from fluidized bed combustion is a saving of lime as the most expensive raw material for the production of aerated concrete. This paper deals about the possibility of fluidized fly ashes utilization in the technology of autoclaved aerated concrete, rheological properties of the mixture, the plastic strength, compressive strength and density of aerated concrete. Another topic of this paper is current state of use and legislative background of use of CCPs in the Czech Republic. Paper also verifies the autoclaving time influence on tobermoritic phase developments and to this related compressive strength of the fly ash aerated concrete.
