| Summary: | The objective of this research project is to substantiate the optimal values of disperse calcium
carbonate waste materials, to ensure their granulation into artificial stone, and to substantiate the
output rate efficiency.
In the course of the research, the authors assessed the lump-forming rate demonstrated by
calcium carbonate waste materials and cement grade CEM I 42,5 N on the basis of their molecular
and capillary moisture capacity. The assessment methodology that defines the threshold of the
lump-forming capacity, as well as the coefficient of output of man-made gravel for different dispersions
of calcium carbonate waste materials have been identified. Data reliability is based on the
mapping of the nature of dependences between the coefficient of lump-forming and the coefficient
of gravel output on specific surface areas.
The authors have identified that calcium carbonate waste materials have a lump-forming factor
that is close or equal to 100%, if its dispersibility is equal to 400-600 m2/kg. In this case, the
highest lump-forming rate is accompanied by the waste fineness of 500 m2/kg.
