Step 4: Correct any imperfections. Now that a large surface area has been smoothed over, an untouched concrete section around the perimeter has been created. This will be caused by the dust-shroud plastic lip, which obstructs the grinding wheel from smoothing the surface close to the wall.

Comminution and especially cement grinding still account for the majority of the electrical energy demand of cement production. As Fig. 12 shows, between 60% and depending on cement properties up to 70% of the roughly 100–110 kWh of electrical energy per ton of cement are used for comminution processes [5], [45]. It has to be noted that …
