DATA REPOSITORY FOR Title: On the quantification of solid phases in hydrated cement paste by 1H nuclear magnetic resonance relaxometry By: Robert Schulte Holthausen & Peter McDonald Submitted to: Cement and Concrete Research Each material-folder names the material investigated and the sample mass in milligrams. Each material-folder contains 9 folders with quadrature-echo pulse sequence files with pulse spacing of 15, 20, 25, 30, 35, 40, 45, 50, 60 microseconds. - The 'acqu.par'-files contain all important measurement information. - The 'data.csv'-files contain three columns with time in microseconds, real-channel-data and imaginary-channel-data. Each material-folder contains 1 folder with T1 saturation recovery - quadrature-echo pulse sequence files with pulse spacing of 25 microseconds. - The 'acqu.par'-files contain all important measurement information. - The 'time1.txt'-file contains the tau1 recovery-times in milliseconds. - The 'time2.txt'-file contains the position of measured data points with t=0 at the middle of the first quadrature pulse in microseconds. - The 'real.csv'-file contains a data-field with the real-channel-data - The 'imaginary.csv'-file contains a data-field with the imaginary-channel-data - The 'complex.csv'-file contains a data-field with the real-channel and imaginary-channel-data combined.

XRD/Rietveld analysis and indentation data

These files are most of the raw data used for our paper on the effect or HCl on chloride binding.

The supplementary thermodynamic modelling results of alkali-activated slag exposed to sodium sulfate and magnesium sulfate.

ANOVA Analysis of the results

Compressive strength reached by samples after different times at different temperatures

Correlation between Sulphur content and loss in magnetic susceptibility between 310C and 325C for 52 concrete and natural samples from Northeastern Connecticut. Status of concrete foundation is also given.

The code can be copied and pasted in matlab [75] or octave [76] and will in return directly plot figure 11 right. The structure is the following: - First the user must write its input parameters. Unless the user need to change the fine details of the code it is the only place that need to be changed to simulate all the plots of the article - The second section deals with the definition of all the variables - The third section deals with the calculation of the volume of CSH - The fourth one calculates the DoH, Heat flow and critical radius from the volume of CSH - Finally, figures are plotted. Comments are already included that help to understand its structure. The associated files are the input PSD and experimental calorimetry curve from Bazzoni herself. They must be saved in the same folder as the code and be named “Bazzoni_PSD.csv” and “Bazzoni_Calo.csv”. If it does not work, try replacing all the commas of these file by semicolon (Windows default software “Notepad” and Mac “TextEdit” can do that automatically).

The Matlab code is the needle model algorithm applied to Bazzoni water to cement = 0.8 experiment. The two other files entitled "Bazzoni_Calo" and "Bazzoni_PSD" are the input files necessary for the code to run; they should be put in the same folder as the code.
