The article is devoted to the problem of obtaining the desired rheological characteristics of the foamconcrete when transporting it by the feeding pipelines to the place of installation in high-rise construction. The dependence of the density change of foamconcrete on the height to which it is transported is shown. It is stated that the use of stabilizers for the foam, as well as certain mechanisms of stabilization results in the concrete mix of the required density. To assess the rheological properties of the concrete mix the coefficient of volumetric relaxation is proposed.
