Title
(EN) METHOD FOR PRODUCING HARDENED BODIES WITH FLY ASH
(FR) PROCEDE POUR PRODUIRE DES CORPS DURCIS AVEC DES CENDRES VOLANTES
Abstract
(EN)
Superior in lightness, water resistance and strength, the hardened bodies which are produced at a very low cost by mixing fly ash and sea water or 3 wt.% aqueous NaC1 solution in a ratio of 72:28 to 55:45 and sintering the mixture at a temperature of 650 to 1,200 °C, can be used as construction materials. They are also used as a soil conditioner owing to the rich minerals in the fly ash, promoting the growth of herbage.
(FR)
L'invention concerne des corps durcis plus légers, présentant une meilleure imperméabilité à l'eau et une résistance mécanique accrue, par rapport aux corps durcis de la technique antérieure. Ces corps durcis sont produits à un coût très faible par mélange de cendres volantes avec de l'eau de mer ou avec 3 % en poids d'une solution aqueuse de NaCl, dans un rapport de 72:28 à 55:45, puis par frittage du mélange à une température comprise entre 650 et 1200 °C. Ces corps durcis peuvent être utilisés sous forme de matériaux de construction et comme conditionneur de sol en raison de la forte teneur en minéraux des cendres volantes pour favoriser la croissance herbagère.
