distribution, thus obtaining a finer and better performing cement. Grinding aids act at two levels: in the mill, with the reduction of cement coating on grinding media and mill lining, and in the separator, with the improvement of classification process. Detailed description of the use of grinding aids in cement industry is reported elsewhere [7].
A multi-state study on noise and texture on PCC pavements concluded that longitudinal texture concrete pavements are among the quietest pavements for interior and exterior noise. Diamond grinding can also remove faults by leveling the pavement surface, thus eliminating the thumping and slapping sound created by faulted joints.
