Abstract
La projection de matières qui sont mélangées avant l'opération de projection à partir de deux courants de matière transportée par de l'air dans une buse de projection a pour résultat des pertes importantes de matière. Ces pertes peuvent être réduites de façon considérable en limitant ou étranglant le courant de l'une des matières et en laissant l'autre courant de matière se dilater lorsqu'il est introduit axialement à peu près au centre du premier courant de matière étranglé, le second courant étant ainsi utilisé pour produire une aspiration par effet d'éjection, cette aspiration agissant sur ledit courant de matière etranglé. Application à la projection de béton renforcé de fibres.
