What's in Your Mix Matters: Your Cement .

As cement clinker is pulverized in a grinding mill, energy in the form of heat is imparted into the finished cement. Consequently, cement plants which are not equipped with cooling systems may market cements with elevated temperatures. The American Concrete Institute (ACI) 225 reports that cement temperatures ranging between 90°F (32°C) and 170°F (77°C) may be utilized in concrete during ...
