VERY FAST SETTING CEMENTITIOUS COMPOSITION WITH HIGH EARLY-AGE COMPRESSIVE STRENGTH
A method of making a rapid setting composition for cement boards is disclosed. Compositions including portland cement, fly ash, gypsum, alkanolamine and phosphate are disclosed. A synergistic interaction between the alkanolamine and phosphate increases the effectiveness of accelerating reactions thus allowing for quick setting and increased early-age compressive strength compositions.
L'invention concerne un procédé de préparation d'une composition à prise rapide pour panneaux de ciment. Des compositions comprenant du ciment Portland, de la cendre volante, du gypse, de l'alcanolamine et du phosphate sont décrites. Une interaction synergique entre l'alcanolamine et le phosphate augmente l'efficacité de l'accélération des réactions, permettant ainsi une prise rapide et une résistance à la compression précoce accrue.
