More Information
Summary:An expansive cement composition including a Portland cement having a calcium aluminate cement additive and a lithium compound additive is provided. The lithium compound additive is capable of producing expansion in set cements when the temperature is at or below room temperature and minimizes the amount of calcium aluminate cement additive needed. L'invention concerne une composition de ciment expansif contenant un ciment Portland ayant un additif sous forme de ciment d'aluminate de calcium et un additif sous forme de composé de lithium. L'additif sous forme de composé de lithium peut produire une expansion dans des ciments ayant fait prise lorsque la température est égale ou inférieure à la température ambiante et permet de réduire au minimum la quantité nécessaire d'additif sous forme de ciment d'aluminate de calcium.
