Abstract
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 approximately 0.001 to 0.1, preferably 0.001, into the composition. 0.05% by weight approximately, based on the weight of the cement, of a synthetic surface active agent having the following characteristics: (a) a cloud point (as previously defined) not exceeding about 80º c; and (b) a "mechanically induced stirred foam height" (as defined above) of less than about 30 mm.
