Slaking occurs when quicklime is reacted with water to form Ca (OH) 2, most commonly called hydrated lime in its dry form or lime slurry or milk of lime in its wet form. The slaking process is exothermic, releasing heat as the quicklime and water mix and chemically combine. A lime slaking system that is not running at its peak could be unsafe ...

Due to the more energyefficient grinding process, Cemex® ground cement will usually have a steeper particlesize distribution curve than corresponding ball mill cements. Consequently, when ground to the same specific surface (Blaine), Cemex® cement will have lower residues on a 32 or 45 μm sieve and tend to have a faster strength development.
