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 μm sieve of less than 15 percent by weight of the blend.
Claims14
A method for treatment of fly ash for preparation of mortars and concretes, said method comprising the steps of:
- blending fly ash with a highly-reactive and dry cement mixture, wherein the cement mixture is obtained by mixing Portland cement with a microfiller and by grinding said cement mixture, and
- grinding the blend in a vibratory milling device to achieve a particle fineness of the ground product that provides a retention on a 45 μm sieve which is less than 15 percent by weight.
Method A method for producing a concrete mixture for preparing concrete structures and elements,
- said method comprising the steps of:
- blending fly ash with a highly-reactive and dry cement mixture, wherein the cement mixture is obtained by mixing Portland cement with a microfiller and by grinding said cement mixture,
- grinding the blend in a vibratory milling device to achieve a particle fineness of the around product that provides a retention on a 45 μm sieve which is less than 15 percent by weight, and
- mixing said fly ash and cement mixture with water and a component selected from the group consisting of sand of greater particle dimensions, aggregates of greater particle dimensions, and mixtures thereof.
