Abstract

Se presenta un aditivo para cemento compuesto de una mezcla de aductos de alquileteroxialquileno inferiores con un material organociclico sulfonado para proporcionar composiciones de cemento de mortero y concreto que inhiben el encogimiento durante el secado mientras se logra un muy alto asentamiento y/o resistencia incrementada a la compresion.
