    • Heat-Resistant Foam Concrete on the Basis of Two-Component Binder 

      Leonovich, S. N.; Sviridov, D. V.; Belanovich, A. L.; Savenko, V. P.; Karpushenkov, S. A. (БНТУ, 2019)
      The composition of dry mix on the basis of two-component cementing agent (aluminous cement and clay of the “Kustikha” field), mineral additives (a metakaolin, the RSAM sulfoaluminate modifier, waste of basalt fiber), Ufapore foamer and the accelerating and plasticizing “Citrate-T” additive is developed. When mixing “Citrate-T” additive with water at Water/Solid = 0.45–0.70, the ...

    • Reinforced Concrete under the Action of Carbonization and Chloride Aggression: a Probabilistic Model for Service Life Prediction 

      Leonovich, S. N.; Shalyi, E. E.; Kim, L. V. (БНТУ, 2019)
      Reinforcement corrosion of marine and coastal hydraulic structures due to chloride aggression and concrete carbonization leads to a sharp decrease in structure safety. The reinforcement is subjected to a depassivation process as soon as a chloride concentration on its surface exceeds a certain threshold concentration, or the pH value in a concrete protective layer is decreased ...
