Investigation of Mineral Hydraulic Binders Based on the Slag-Cement System Obtained with the Use of Vortex Electromagnetic Homogenization

Samples of mineral hydraulic binder and artificial stone based on such binder were obtained from granulated blast furnace slag and Portland cement M500 using vortex electromagnetic homogenization. The following physico-chemical characteristics of mineral powders have been investigated: phase and chemical composition, specific surface area, particle size distribution, mechanical properties of artificial stone based on the slag-cement system binders. It is shown that the introduction of 10 to 50 wt.% of Portland cement into the composition of the developed materials results in the variation of ultimate compressive strength of the samples from 50 to 90 MPa, and density variation from 2.1 to 2.5 g/cm 3 . These materials have low cost due to the use of blast-furnace slag as a raw material along with an energy-efficient grinding technique.
