Abstract
A method for treatment of fly ash for incorporation into and for preparation of mortars and concretes. Fly ash is intensively blended with a highly reactive and dry cement mixture that is obtained by mixing Portland cement with a microfiller and possibly a water reducing agent. The blend of fly ash and Portland cement is then ground in a vibratory milling device to achieve a final product fineness having a particle size to provide retention on a 45 .mu.m sieve of less than 15 percent by weight of the blend.
