“…This forms a very dense cement stone, in which the smallest partially sealed pores are evenly distributed. As a result, the strength indicators, water resistance and frost resistance of the resulting material are significantly increased, which is confirmed by comprehensive studies [9][10][11].…”

Power transmission lines (PTL) are strategic objects, the reliability of which depends on the life support of the country. Most of the currently operated power transmission lines were put into operation in the twentieth century, and by now there is a problem of assessing their technical condition, repairing them, if necessary, and maintaining them in a working condition. Defects that appear during the operation of reinforced concrete elements of power transmission lines have different localization and degree of manifestation, but typical is the destruction of the surface layer of concrete with exposure of rebar, more often at the base of the power transmission line. The aim of the work is to select the optimal composition of the repair mixture based on non-shrinking and expanding cements, ensuring reliable adhesion of the repair compounds to the concrete of the structure, which will restore the bearing and operational characteristics in the repaired reinforced concrete elements of the power transmission line at the design level.

In this paper the issues of creation of effective composite materials for performance of repair and restoration works of operated reinforced concrete structures are considered. The necessity of introducing repair compositions is justified. Theoretical foundations of concrete mixtures preparation process are given. Original repair compositions developed by the authors with an expansion additive based on Portland cement, as well as substandard fine aggregates with increased physical and mechanical properties of concrete are proposed
