Intensification of Technological Processes of Winter Concreting of Monolithic Buildings
The aim of the study is to formulate complex principles of intensification of technological processes of winter concreting of monolithic buildings, providing a reduction in construction time and improving the quality and safety of monolithic structures. To achieve this goal, the following problems were solved: the existing methods of preventing water crystallization into concrete were considered; the dependences of the maximum permissible parameters of winter concreting on the compressive strength of concrete during its aging were established; the minimum permissible (“critical”) strength of self-compacting concrete at the time of freezing is determined; it is found that it is less in comparison with conventional vibrated concrete of the same class in compressive strength. The findings are practical recommendations for the preparation and laying of concrete mix in winter conditions.
