“…For example, the Si map shows pixels with a range of gray values which indicates varying concentration of Si across the map i.e., presence of different silicates. The Si weight concentration is the highest in quartz (0.47), followed by orthoclase (0.3), albite (0.32), hornblende (0.21–0.23) and biotite (0.17–0.21) 39 and the same trend can be seen in the Si EDS map as well. Similarly, other elemental maps show elemental presence only in the region where the minerals which have these elements are present.…”

“…This map shows the Si relative weight concentration at every point in the scan area for which phase assignment was done using theoretical values based on known chemical formulae 39 with a tolerance of 0.015%. For minerals such as biotite and hornblende which occur as a series of minerals in nature with known end-members 40 , the corresponding Si weight % ranges were used.…”

“…As many of the minerals that compose the cement paste and aggregates contain many of the same elements in similar ratios and due to the uncertainties in the weight concentrations provided by elemental quantification techniques, the thresholding of these values can be challenging and often require combining several tech-niques. Further information regarding the use of combining volume fraction of phases obtained by Rietveld refinement of X-ray diffraction (XRD) data and XRF data in MOSAIC can be found in (Li et al 2020). with 10-50 µm resolution.…”

“…The IPI's RIVE model and parameters are also determined using homogenization techniques based on the minerals' volume fractions determined experimentally and their respective RIVE models. The HCP Young's modulus is 12 GPa, and its Poisson's ratio is 0.2 [8].…”
