METHOD OF PORTLAND CLINKER GRINDING FOR PLASTERLESS PORTLAND CEMENTS PRODUCTION

摘要

The invention relates to admixtures and a method for milling Portland clinker for the production of gypsumless Portland cements with specific surfaces of from 350 to 750 m<2>/kg. According to the invention, the milling is carried out in the presence of 0.01 to 0.15 mass-% of a synthetic organic surface-active substance with wetting properties which is stable in alkaline media of pH values 9 to 12.
