To ensure sustainable concrete building industry it is necessary to decrease consumption of natural resources for manufacture of concrete and reduce content of CO2 produced during production of cement. This approach has not only ecological impact on future activities but it can also considerably reduce cost of concrete. In the Czech Republic, about 6.5 million tons of high quality fly ash is produced during classic high temperature combustion of anthracite or brown coal for production of electric energy. Fly ash produced in such way has high content of SiO2 and low content of CaO, and it is ranked among co-called siliceous fly ash, which has outstanding pozzolanic properties. This paper describes experience from experimental development of High Volume Fly Ash Concrete (HVFAC), where over 50% of fly ash is used as substitution of Portland cement for binder. High proportion of replaced Portland cement were tested in this research; impacts on strength of concrete at the age of 7 – 180 days, consistency of concrete and other related properties were observed.
