Q. What methods are used for protecting concrete against low temperatures? A. Methods range from a simple covering of blankets to the use of accelerating admixtures, initial heating of the materials, or elaborate heated enclosures. The simpler methods are used when cold weather overtakes a job about to be completed or one is started in the belief that warm weather is about to arrive. It is when makeshift provisions are employed that unsatisfactory results are likely to follow. With well-planned operations, concrete has been placed safely in temperatures well below –20°C (–4°F).
