Excerpt from Concreting in Winter But many large contracting companies, who have carried on their con crete work uninterruptedly with results as satisfactory as obtained during more favorable weather conditions, have proved that concreting is possible during periods of freezing weather if proper, simple precautions are taken. A knowledge of this has made the subject of concrete construction in winter of general interest to many users of cement; in fact, since it is a slack season many have found winter the best time of year for them to build with concrete. However, successful results depend upon exercising certain additional precautions beyond those that must be Observed during other seasons of the year. The object of this publication is to describe methods that should be followed to insure success in concreting carried on during cold weather.

Excerpt from Concreting in Cold Weather Before placing concrete in cold weather forms should be thoroughly cleaned of snow, ice or particles of frozen concrete. Metal forms should always be heated. In extremely cold weather wood forms also should be heated. Turning a jet of steam against form faces is best when available.
