A record-breaking heat wave is stretching across most of the United States this week, with about 195 million people under watches and warnings as temperatures peak today and into the weekend.
More than 85% of the lower 48 state’s population will see temperatures above 90 degrees Fahrenheit over the next few days, according to CNN meteorologist Dave Hennen, and more than half will see temperatures higher than 95 degrees.
But for those working outdoors, these extreme temperatures are unavoidable—the job still must get done. Besides the risk of experiencing symptoms of heat-related illnesses such as heat cramps, heat rash, heat exhaustion, fainting and  heat stroke, concrete contractors also face numerous challenges when temps rise.
Placing concrete in extreme weather means managing complications such as accelerated slump loss, plastic shrinkage cracking and faster set times.
