MAGNETIC FIELD AS CONTROL FOR THE STRUCTURE AND PROPERTIES OF CEMENT SYSTEMS. PART 2. STRUCTURAL PROPERTIES OF MINERALS AT CEMENT BRICK EARLY HARDENING USING MIXING WATER MAGNETIC ACTIVATION
Abstract
The paper presents the quantification phase analysis of cement brick after a day of its natural hardening in the original state and after 15 and 25 cycles of magnetic activation of mixing water. The phase analysis is carried out using the Rietveld method. The energy computations of crystal lattices of Portland cement phases are provided to analyze the influence of magnetic activation on phase formation at cement paste hardening and the structural state of Portland cement components. Energies of Portland cement phase lattices are computed at 0 K at the initial stage of hardening (for one day). It is shown that the magnetic activation of mixing water has a considerable effect on the quantitative phase composition and the crystal lattice energy after 15 and 25 cycles of magnetic activation in comparison with the original state of cement system.
