Data for “Quantifying rheology and microstructure of hydrating Portland-Limestone Cement blends to address additive manufacturing needs”

These data are associated with the paper “Quantifying rheology and microstructure of hydrating Portland-Limestone Cement blends to address additive manufacturing needs” by the same authors [1]. The data are associated with in situ dielectric rheological small-angle neutron scattering (rheo-SANS) studies of Portland limestone cement (PLC) blends and Ordinary Portland Cement (OPC) control [2]. The rheo-SANS data were collected on the NIST Center for Neutron Research (NCNR) VSANS instrument [3] as a function of cement hydration time. The datasets comprise: (i) in situ small amplitude oscillatory shear (SAOS) rheology data during SAOS frequency sweeps versus hydration time; (ii) corresponding dielectric impedance spectroscopy [4] data during AC frequency sweeps versus hydration time; (iii) in situ rheo-SANS data with microstructural model fits and associated fitted model parameters versus cement hydration time; and (iv) further experimental data with Avrami model fits associated with cement hydration heat output and selected rheo-SANS microstructure model fit parameters.
