Grinding of the Clinker without Sulfate Carrier . The clinker was initially crushed to a particle size of approx. 4 mm. The concentration of different polymers A specified in Table 5, based on the clinker, were added to the clinker (400 g) and, without addition of gypsum, ground in a laboratory ball mill from Fritsch without external heating at a rotational speed of 400 revolutions per minute.

Concrete grinding residue increased soil pH, alkalinity and electrical conductivity. Offloading of CGR elevated the concentrations of Ca, K, Mg, Na, Al and Fe in soil. The effects of CGR on soil were not significant after application over one year. The effects of CGR on soil were mitigated at deeper soil layers.
