Cemex Activa is a powdered form additive, developed specially for the sector of cement industry to increase strength, reduce setting time and improved mill performance.
The method of operation is that it interrupts the normal retardation between gypsum and tricalcium aluminate phase of portland cement with reduced setting time. This allows the tricalcium silicate reaction to begin sooner than the normal and ultimately result in significant early strength increase.
The product also reduces the electrostatic attraction between broken particles in the mill system, this in turn, reduces agglomeration within the mill. In turn makes more energy available for actual grinding of particles thus enhancing mill performance to give higher throughput. Dosage may vary from 0.5% to 1% by mass of cement.
