AB  - Fine ground cement is a kind of composite binders with a specific surface of 500-550 m<SUP>2</SUP>/kg with a clinker component partially replaced by a silica-containing component (quartz sand, ash, slags, volcanic tuff, etc.). Based on the world-outlined tendencies towards the refocusing of building materials industry to the concretes with low cement content this type of binder shows promise. One of the main factors hampering the widespread of fine ground cements is the increased energy consumption associated with the grinding of its components. During the research we identified patterns of change in the duration of the grinding and the compressive strength of these binders with different contents of siliceous component (quartz sand) depending on their manufacturing method. The possibility of reducing the duration of the production process of fine ground cement by 30% while increasing their compressive strength by 20% was proved.
