METHOD FOR PRODUCING A CEMENTITIOUS COMPOSITION IN POWDER FORM

A method for manufacturing a cementitious composition comprising a) uniformally fluidising in a container, particles of a substantially dry powdered cementitious composition by creating aerial motion of the particles by rotational motion perpendicular to the fall of the particles, b) at the same tim...

Beschreibung
Zusammenfassung:	A method for manufacturing a cementitious composition comprising a) uniformally fluidising in a container, particles of a substantially dry powdered cementitious composition by creating aerial motion of the particles by rotational motion perpendicular to the fall of the particles, b) at the same time uniformally spraying the particles with 0.1 to 10 parts by weight (per 100 parts of cementitious composition) of water, optionally containing a cement admixture, and c) mixing the particles and the water intensively by shearing forces.
