The method for synthesizing a new efficient organic-mineral additive for cement systems is proposed. Studies of modes of obtaining the additive under conditions of limited access of air are presented. It is shown that in case of introducing the additive on the basis of peat, produced at 600оC, into the cement system, the significant improvement of strength and hydro-physical characteristics of cement stone is achieved. Results of the X-ray structure phase analysis show that the product, generated during the process of peat treatment at 600оC, contains various phases in the nano-disperse state, including fullerenes and other forms of nano-carbon which change the kinetics and mechanism of the interaction of cement with water and subsequently lead to improving the strength, water resistance and frost resistance of the cement stone.
