Within the framework of theory of sliding of the micro-polarized environment, developed by V.N. Rudakov,norms of СНиП 2.03.01-84*, norms of Russia СП 101-2003 and norms of Ukraine ДБН В.2.6-98:2009 correlations of physical-mechanical descriptions of heavy concrete of classes B20…B60 with the purpose of analytical determination of corner of sliding ö and durability Rbtn. Cube durability Rbkn is certain by value Bi with normative confiding probabilityVbkni = (1 −1,64 × 0,135 × 0,01Bi ) . As a result of calculation have, according to the class of concrete, corner ф ≡ 65...69° , and value Rbtn, on the whole, coincided with normative for seven classes, and for the classesof B40 and B50 divergence made, in the quantitative measuring 0,05 MPa, and in a percent a bout 2 %. Taking into account the mixed character of destruction of concrete, the attempt of determination of resistance the cut of Rbsn is done for the concrete of middle durability on a formula Rbsn = Rbtn ⋅ tgф . In the total the results of our calculations practically coincided with information of early researches of V. A. Bushkov, V. Y. Rutgers and other.
