摘要

This report presents nearly 200 low temperature calorimetry (LTC) scans performed on hydrating portland cement pastes between 2002 and 2005. Because the LTC scans provide valuable information on the percolation of various size pore networks within the hydrating cement pastes as well as the quantity of freezable water as a function of temperature, it was decided to present a compilation of the plots of all of the LTC results obtained over the course of several research projects. Variables include water-cement mass ratio (w/c), curing time, curing temperature, saturation, and limestone and alkali additions. Each plot is characterized by the portland cement used, the mixing solution used, the w/c, the curing temperature, the measured degree of hydration (when available), the curing conditions with respect to saturation, the specimen age when tested, the specimen mass, the filename of the raw LTC data, and the testing date of the LTC run. The experimental procedures used to prepare and evaluate the samples are briefly presented, along with a set of observations obtained from interpretation of the numerous individual data sets.
