Conclusions

  1. 1.

    Existing methods do not enable us to assess the degree of homogeneity of materials with sufficient rapidity and high accuracy.

  2. 2.

    The Department of Structural Materials of the V. V. Kuibyshev Moscow Structural Engineering Institute has developed a rapid method (the labeled components method) permitting an objective assessment of the uniformity of concretes for hydraulic structures.

  3. 3.

    Using the method of labeled components, the authors have shown that surfactants improve of concrete mixes and also prevent separation and loss of uniformity during transport and placing.
