Abstract

Additif fluidifiant pour les plâtres, permettant de diminuer la quantité d'eau nécessaire au gâchage. Cet additif consiste en un condensat d'acide naphtalène-sulfonique à l'état de sel de potassium, à un poids moléculaire d'environ 300 à 3 000, et à une teneur en potassium d'environ 0,10 à 30 % en poids, exprimé en K2 O. L'additif selon l'invention permet de diminuer considérablement les quantités d'eau nécessaires au gâchage sans nuire aux propriétés physiques des produits durcis.
