<p><P>PROBLEM TO BE SOLVED: To provide an improved method for treatment of fly ash for production of mortar and concrete. <P>SOLUTION: The method is characterized in that, in a first step, fly ash is intensively blended with a highly-reactive and dry cement mixture, which mixture has been obtained by mixing portland cement with a microfiller and possibly a water reducing agent and by grinding the mixture, and in that, in a second step, the so obtained blend is ground together in a vibratory milling device to achieve the fineness of the final product with retention on a 45μm sieve which is less than 15 percent by weight. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
