Abstract

Procedimiento para la producción de una composición de cemento hidráulico, de modo que el cemento hidratado, preferiblemente cemento Portland, tenga una resistencia a la compresión mejorada, caracterizado porque comprende introducir en la composición de 0,001 a 0,1 aproximadamente, con preferencia de 0,001 a 0,05% en peso aproximadamente, basado en el peso del cemento, de un agente de superficie activa sintético que tiene las siguientes características: (a) un punto de turbidez (como anteriormente se ha definido) no superior a 80ºC aproximadamente; y (b) una "altura de espuma agitada mecánicamente inducida" (como anteriormente se ha definido) inferior a 30 mm aproximadamente.Process for the production of a hydraulic cement composition, so that the hydrated cement, preferably Portland cement, has an improved compressive strength, characterized in that it comprises introducing into the composition from approximately 0.001 to 0.1, preferably from 0.001 to About 0.05% by weight, based on the weight of the cement, of a synthetic surface active agent having the following characteristics: (a) a cloud point (as defined above) of not greater than about 80°C; and (b) a "mechanically induced stirred foam height" (as defined above) of less than about 30 mm.
