The analysis of modern lines in the field of research and working out complex organicmineral additives for regulation of properties of concrete mixes and concrete is presented. It is shown, that a perspective direction of the further researches is expansion of a raw-material base of mineral and chemical components organic-mineral additives, and also reception of new kinds of complex additives, in that, number of additives for giving to concrete of special properties. Spent theoretical and experimental researches have shown possibility of realisation of a problem of increase of efficiency organic-mineral additives for regulation of properties of concrete mixes and concrete. It is established, that application developed organic-mineral additives allows to raise strengths indicators of a cement stone, to provide the accelerated set of durability in early terms hydration, and also to provide a set of durability of a cement stone at negative temperatures.
