Abstract

Procedimiento para mejorar la elaboración y las resistencias mecánicas iniciales de composiciones de cemento hidráulico, en especial a temperaturas tan bajas como 0º a 15ºC, caracterizado porque consiste en tratar dicha composición con un agente dispersante perteneciente al grupo constituido por sales hidrosolubles derivadas de los productos de condensación de ácidos sulfónicos aromáticos con el formaldehído, de cuyo peso molecular comprendido entre 1.500 y 10.000, siendo utilizadas dichas sales solas o mezcladas con sales hidrosolubles derivadas de ácidos sulfónicos aromáticos, y esencialmente, añadir además a la composición una mezcla de hidróxido de litio con un hidróxido de litio con un hidróxido de otro metal alcalino o alcalinotérreo.
