ABSTRACT:
An exemplary method of the invention comprises introducing into a grinding mill, wherein cement clinker is ground to provide cement powder, a diamine such as tetrahydroxylethylethylene diamine, and an alkanolamine such as triethanolamine or triisopropanolamine. The combination of the diamine and alkanolamine provides superior grinding efficiency compared to diamine or alkanolamine added separately.
