GEOMETRICAL MODEL AND FORECASTING PROPERTIES OF FOAM MORTAR

General model is formed by forma-lization of foam mortar structure: from realis-tic to model. Formalization based on number of successive hypotheses which take into account validity check of obtained results which are enounced in the article.

The predictability of foam mortar properties are reviewed in the article using the general model. As a critical characteristic of foam mortar was adopted pinhole rating. The analytic dependence relating to the pinhole rating, structural features, properties of mineral matrix with durability and thermal conductivity of foam mortar are obtaining. Article presents the separately solved task about thermal conductivity of wet material. According to the modeling results accomplished the graphical interpretation and plotted the pooled nomogram.

Key words: modeling, structure, foam mortar, matrix, thermal conductivity, pinhole rating, strength.
