Probabilistic distribution of dissolution rate constants for cubic tricalcium aluminate in water

The probabilistic distribution of dissolution rate constants for cubic tricalcium aluminate (C3A) in water was quantified based on in-situ measurements of the changes in the nanoscale surface topography using reflection digital holographic microscopy. Measurements were performed on polished sintered pellets of C3A from two sources. C3A#1 consists of 94.2 % crystalline C3A-c, 2.0 % free CaO, and 3.8 % amorphous content. C3A#2 consists of 84.3 % crystalline C3A-c, 1.0 % free CaO, 4.6 % mayenite, and 10.1 % amorphous content. The data presented in the two text files, labeled C3A#1 and C3A#2, have two columns of values corresponding to the probabilistic distribution (histogram) data; the first column is the frequency and the second column is the rate constant value in units of umol m^-2 s^-1. All uncertainties associated with this dataset are discussed in an accompanying paper.
