Influence of complex acoustic-radio wave treatment of water on an index of activity of ions of hydrogen, rheological specifications prepared by a cement-sand mixtures and technological parameters of the obtained plasticized fine-grained concrete studied. Two methods used to reach the maximum influence on an index of activity of ions of hydrogen of water, mobility, keeping of the prepared concrete compounds, density and durability at compression of concrete. The first method – four -minute complex acoustic-radio wave treatment of water (high frequency (5.28 MHz) ultra sound (44 kHz)), with the subsequent four minute additional impact of a high-frequency field. The second used method – four-minute complex treatment of water (high frequency (5.28 MHz) ultra sound (1 MHz)) with the subsequent two-minute additional impact of a high frequency field. Assumptions about the mechanism of acoustic-radio-wave activation of water and its impact on the process of hardening and structure of Portland cement systems are stated.
