Conclusions

  1. 1.

    Dry grading of sand-gravel mixes during the winter, in combination with special hydraulic stockpiling, is an effective procedure for construction in the northern regions.

     
  2. 2.

    The quality of the concrete prepared during the winter, with temperatures of the coarse fraction as low as −10°C, is not inferior to the quality of the concrete prepared during the summer.

     
  3. 3.

    Thermal resistance of the “warm” formwork of 1.5 (m·h·°C)/kcal is sufficient to ensure crack resistance os structures concreted during the winter. For blocks measuring 11×12m, concreted during the summer, it is possible to use “cold” forms to provide additional cooling of the concrete down to temperatures of 10–15°C, before the approach of the winter.

     
  4. 4.

    To reduce the labor costs involved in the concreting work during the winter, it is necessary to improve and unify the formwork and tent elements.
