Substantiation of One of the Methods for Improving the Structure of Foam Concretes

The relevance of development of the theory and practice of gas-filled concretes is reflected. It is shown that till now the modern construction materials science doesn’t have the necessary volume of knowledge, relying on which the design of the composition of foam concretes is possible. Differences in the features of the formation of the structure of interporous partitions in foam- and fibrous foam concrete mixes are considered from the position of the theory of fractal clusters. It is shown that the length of the fiber is the most important parameter that predetermines the sizes of clusters formed in inter-porous partitions of gas-filled concrete. It is the length of the fiber that causes an increase in the density of inter-porous partitions and the value of plastic strength in foam concrete mixtures.
