Abstract
1. Cohesion in the working joint of a monolithic structure when pouring concrete on a frozen foundation can be provided by using an addition of sodium nitrite to the concrete. 2. The magnitude of cohesion in the joint at negative temperatures is within approximately the same strength limits of a monolith as at positive temperatures and depends on the type of preparation of the foundation and methods of treating the joint. 3. The use of brushing of the surface of freshly-poured concrete during its setting period gives better results with respect to cohesion of concretes than the use of scoring. 4. Data from the laboratory experiments indicate the expediency of using the method of pouring concrete with sodium nitrite on a frozen concrete foundation at individual installations.
