Chemical admixtures that can extend the temperature range at which concrete can be placed, thus expanding the construction season, have been developed at the Cold Regions Research and Engineering Laboratory in Hanover, New Hampshire. CRREL offers preliminary guidance to enable military and civil engineers to design, from readily available chemicals, cold-weather concrete admixtures that are suited to their particular structural and environmental requirements.
Antifreeze concrete is
- Structurally comparable to conventional concrete
- Resistant to freezing and thawing
- Predictable to formulate and test for quality
- Cost-competitive with conventional concrete
- Capable of preventing frost damage during cure.
Concrete is the backbone of modern construction. CRREL provides guidance on chemical admixtures that allow concrete to be placed, finished, and set up at temperatures as low as -14F (-10C) without the need for heated enclosures, insulation blankets, or other forms of thermal protection, which are expensive in terms of both labor and money and are especially difficult and expensive for pavements.
