In the next state of the process, clinker is cooled in coolers. The hot air from the coolers is returned to the pre-heater in order to save fuel in the overall process. The clinker is then ground to produce portland cement. Gypsum is added during the grinding process to control the set rate of the cement.
Aug 21, 2014· Polished concrete flooring is simply a concrete floor that has been treated with a chemical densifier (to fill in the holes/pores) and ground down (similar to sanding wood) with progressively finer grinding tools.
