Title (EN) MANUFACTURE OF ARTICLES FROM FLY ASH
(FR) PRODUCTION D'ARTICLES A PARTIR DE CENDRES VOLANTES
Abstract: front page image
(EN)The present invention provides a method of forming a shaped article having a matrix that contains sintered fly ash. The method comprises the step of blending fly ash together with water to produce a fly ash dough. The water is added in excess of that which is absorbed by the fly ash so that the dough contains free water so as to be in at least a partially fluid state. The method also comprises the steps of forming a green article in a desired shape from the fly ash dough, and removing at least a portion of the free water from the fly ash dough during and/or after forming of the green article. The green article is subsequently fired so that the shaped article is hardened by sintering its fly ash matrix.The present invention also provides a building element having a matrix of sintered fly ash.
(FR)L'invention concerne un procédé pour former un article présentant une matrice contenant des cendres volantes frittées. Ledit procédé comprend le mélange des cendres volantes avec de l'eau pour former une pâte de cendres volantes. La quantité d'eau ajoutée ensuite est supérieure à la quantité absorbée par les cendres, de sorte que la pâte contient de l'eau libre, ce qui permet de la rendre partiellement liquide. Ledit procédé comprend également la formation d'un article vert dans une forme souhaitée à partir de la pâte de cendres volantes, et l'élimination d'au moins une partie de l'eau libre de la pâte de cendres volantes, pendant et/ou après la formation de l'article vert. Ledit article est ensuite enflammé, de façon à ce qu'il durcisse lors du frittage de la matrice de cendres volantes. L'invention concerne, de plus, un élément de construction présentant une matrice de cendres volantes frittées.
