Appears on pages(s):
An apparatus for measuring continuously the rates and total amounts of heat liberated when cement compositions and water react at temperatures in the range of 80 to 350 F and at pressures from atmospheric to 10,000 psi is described. The method of calibration and test procedure are given. Typical test results obtained on portland cement pastes cured at 100 F and at various pressures show that the rates and total amounts of heat liberated are increased by pressure at early ages.
