The influence of grain composition and active mineral addition of microsilicasuspension on properties of dry concrete mix was considered. The selection of the method of production of paving slabs with allowance for technological modes of vibropressing technology was made. The optimum dose of microsilicasuspension, having positive effect on the concrete quality, was defined.
