Abstract
One of the main options in looking for the new building materials is using of wastes from an industry as a replacement of the existing ingredient. This way is used in the concrete production too. Basic effort is to find a suitable replacement for economically and ecologically unfavorable cement by another component or components. As one of these components can be used fly ash – by-product of coal-fired electric power stations. The using of the fly ash as an additive into concrete is quite old, nevertheless this component offers a lot of new possibilities today too. Mechanical activation is one of them. As mechanical activation is known sorting or grinding of fly ash. Activation by sorting brings some disadvantages as is not using of all production and the high price for rebuilding the plants. Much more effective option provides grinding of the fly ash. This practice also comes to Czech Republic and submitted publication summarizes existing knowledge and presents result from first tests done on Czech fly ashes.
