Cement Mill Exit Temperature Standards - wildcer.org.in

Cement produces heat as it cures through the heat of hydration chemical reaction. As a result, cement tops can be located if a temperature survey is run before the setting cement cools, usually logging 12 hours or so after the cement is placed is a good choice. Squeezed cement can be frequently located, but a differential log may be necessary.
