  1. 1.

    The quality of the cement and aggregates and slump of the concrete mix met the requirements of the technical specifications of the construction of the Kirovskoe reservoir.

  2. 2.

    Both concrete grades correspond to the design requirements with respect to compressive and cleavage tensile strengths, density, and impermeability. The probability of the design grade with respect to compressive strength is 97–99% and cleavage tensile strength 99%.

    There are firm grounds to consider that the concrete of the dam meets the design requirements with respect to frost resistance.

  3. 3.

    The homogeneity of both concrete grades, evaluated by the coefficient of variation of compressive strength, should be considered good.

  4. 4.

    An explicit improvement of concreting technology was observed as the years of construction passed, which is indicated by the data on the homogeneity of the concrete.

  5. 5.

    A comparison of the quality of concrete confirms the technical expediency of reducing the consumption of cement for concrete grade 25 MPa from 265 to 240 kg/m3 and for concrete grade 20 MPa from 240 to 225 kg/m3. Furthermore, this measure saved 97,500 rubles.
