Annotation: The paper covers the results of studying mass transfer characteristics of ash gypsum cement binding agents. The results allowed concluding that the matrix of the ash gypsum cement binding agent stone in its structure and moisture transfer characteristics is more close to a cement stone than the matrix of gypsum pozzolana cement. A possibility of a further use of the products based on the ash gypsum cement binding agents for outdoor application under different climatic conditions was determined by using a complex analysis of the results of measurements of the basic physico-mechanical characteristics and the investigation of kinetics of water adsorbed by capillarity by the samples. A series of comparative experiments was held on the samples of the ash gypsum cement binding agents in which the fly ash from a TPP was used as a pozzolanic additive on the contrary to the gypsum slag Portland cements in which the slag Portland cement was used as a pozzolanic additive. The results of this study allowed to conclude that kinetics of water adsorption by all the samples of the ash gypsum cement binding agents was similar. The height of the water adsorbed by capillarity in all measurements in the samples from the ash gypsum cement binding agents was higher than that of the reference samples. However, the difference in the heights of water adsorbed by capillarity in the samples under study was very small. These results allowed making a conclusion that in the process of service under similar conditions the performance properties (frost resistance, durability and other basic physico-technical characteristics) of the products made of the ash gypsum cement binding agents are very close to those of the products made of the gypsum slag Portland cements.
Keywords: mass transfer, ash gypsum cement binding agent, moisture transfer characteristics, fly ash, durability, frost resistance.
