aggregate exposed by the grinding. While both the aggregates and the concrete matrix contribute to the final appearance, it is the aggregate rather than the matrix which holds the polish. Hard igneous rocks are the most suitable for honed (and polished) finishes as they resist wear and therefore tend to hold the smooth finish.
That would make the most sense.Grinding down exposed aggregate just seems like opening a can of worms. Grind too little and you now expose more sharp edges, grind too much and you have a slick surface (much like poured concrete flooring) that is a huge headache in wet areas.
from floor to floor) If the aggregate is deep it will not be worth grinding that deep. Running the grinder at a low RPM may increase grinding speed in the course steps (14 and 30 Grit) by allowing the diamonds to penetrate the floor without overheating. This is most effective on soft concrete or concrete less than a year old. Experiment with speed
After the wetting stage, it is necessary to de-aggregate and deagglomerate the pigment particles. This is usually accomplished by mechanical action provided by high impact mill equipment. In the grinding stage, the cohesive forces inside the agglomerates have to be overcome.

Epoxy terrazzo rough grinding is done dry with vacuum systems to collect the grinding dust. In contrast, cement terrazzo is wet-ground so a grinding slurry is created. After the floor is rough ground until the metal or plastic divider strips are exposed and the aggregate is uniformly exposed, both systems are grouted.
A significant change in viscosity was observed especially at the lowest particle sizes, which was the only point where the difference between grinding with and without TEA was obvious. At high shear rates, no difference was observed between grinding with and without TEA so aggregates with higher strength were present and remained intact.
