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.", "distribution": [{"accessURL": "https://doi.org/doi:10.18434/M3SW2G"}, {"downloadURL": "https://s3.amazonaws.com/nist-midas/1843/C3A%231.txt", "mediaType": "text/plain"}, {"downloadURL": "https://s3.amazonaws.com/nist-midas/1843/C3A%231.txt.sha256", "mediaType": "text/plain"}, {"downloadURL": "https://s3.amazonaws.com/nist-midas/1843/C3A%232.txt", "mediaType": "text/plain"}, {"downloadURL": "https://s3.amazonaws.com/nist-midas/1843/C3A%232.txt.sha256", "mediaType": "text/plain"}], "identifier": "50FF29D41202478EE0531A57068105821843", "keyword": ["dissolution", "kinetics", "portland cement", "rate constant", "tricalcium aluminate"], "landingPage": "https://data.nist.gov/od/id/mds2-1843", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2017-06-02 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "references": ["http://dx.doi.org/10.1021/acs.langmuir.7b02400"], "theme": ["Materials:Ceramics", "Materials:Concrete/cement", "Materials:Materials characterization", "Mathematics and Statistics:Image and signal processing"], "title": "Probabilistic distribution of dissolution rate constants for cubic tricalcium aluminate in water"}
