DIMENSIONAL CHANGES OF HARDENED PORTLAND CEMENT PASTES CAUSED BY TEMPERATURE CHANGES

A THEORETICAL BASIS FOR EXPECTING THE MOISTURE DISTRIBUTION IN WATER-SOAKED HARDENED PORTLAND CEMENT PASTES TO CHANGE WITH TEMPERATURE IS PRESENTED. THE THEORY PREDICTS SHRINKAGE AFTER WARMING AND SWELLING AFTER COOLING. A METHOD FOR MEASURING LENGTH CHANGES OF PASTE SPECIMENS DURING AND AFTER TEMPERATURE CHANGES IS DESCRIBED. THE RESULT OF DIMENSIONAL CHANGE MEASUREMENTS ARE CONSISTENT WITH THE THEORY PRESENTED, AS ARE ALSO THE WEIGHT CHANGES OF SPECIMENS SATURATED WITH WATER AT 25 C AND 0 C. THE INITIAL DILATIONS PRODUCED BY FREEZING WATER-SOAKED PASTES, LIKEWISE, SHOW THE EFFECT OF MOISTURE DISTRIBUTION CHANGES. /AUTHOR/
