Hot Weather Concrete

The American Concrete Institute (ACI) defines ‘Hot Weather’ as high ambient temperatures, high concrete temperatures, low relative humidity, high wind speed, solar radiation, or any combination that will impair the quality of concrete due to accelerated moisture loss and/or cement hydration. Most summer days in New York State would qualify as ‘Hot Weather’, using ACI’s definition.
