Some mixes can tolerate heat better than others. With concrete maturity testing, one can monitor the performance of concrete cured at high temperatures to ensure sufficient strength. For example, some high-early strength mixes cure very well at high temperatures (sometimes as high as 170°F!).
Curing the initial lab cylinders at high temperature (as tracked by the concrete maturity meter) will give a clear picture of the actual performance under high temperature field conditions, and can identify problems before the job starts.
