Abstract

The paper proposes a synthesis method of a new effective organo-mineral admixture for cement systems. The study of the admixture production modes at 600 °C and 400 °C in conditions of limited air access is described. It is shown that introduction to the cement system of the peat-based admixture produced at 600 °C allows to achieve a significant improvement in the strength and hydro-physical properties of the cement stone. It is established that the optimal peat processing temperature for production of modifying admixtures is nearly 600 °C. The results of the X-ray phase analysis showed that the product, formed during peat processing at 600 °C, contains in its structure various phases in a nanodispersed state, including fullerenes and other types of nanocarbon. It is shown that the presence of nanocarbon particles change the kinetics and the mechanism of cement and water interaction and, as a consequence, lead to an increase in the strength, water-resistance, and frost-resistance of the cement stone.
