“…The following step will determine which oxides are present in which phases or create solid solutions. Assigning the oxides to their appropriate phases based on known phase compositions [14,34]. Minor oxides (<5 wt% of the bulk composition of the BOF slag), such as V2O5, Cr2O3, P2O5 TiO2, are categorized into a single phase in agreement with their dominant partitioning behaviour.…”

An industrial by‐product of the steel industry called basic oxygen furnace (BOF) slag has recently undergone extensive research for high‐end applications outside of road load and landfill. In contrast to the Bogue methodology used with regular Portland cement, BOF slag lacks a quick and straightforward quantitative phase analysis procedure that would allow it to be employed as a high‐end raw material. The main phases of BOF slag (C2S, C2(A,F), Ff, RO‐Phase, and f‐C) can be calculated using the method presented in this paper based on chemical composition.

“…For the Rietveld quantitative phase analysis, Table 3 lists the structures that were taken from the ICDS or PDF database along with the stoichiometry for each structure. For Rietveld quantification the actual measured compositions of the slag phases are used as the derived with EDS-Spectral Imaging and PARC quantification [14,34].…”

Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM‐EDS) is an indispensable and versatile technique that provides detailed 2D spatial insights into the microstructure of heterogenous cementitious systems. To foster clear and systematic understanding of SEM‐EDS analysis in advancing research on cementitious materials, the state‐of‐the‐art principles, analytical approaches, and applications of SEM‐EDS analysis in cementitious systems are reviewed. This review aims to assist researchers in selecting the most appropriate strategy for SEM‐EDS analysis to quantify phase assemblage, elucidate environmental interactions, and investigate microstructure evolution in cementitious systems. The fundamental concepts related to equipment, signal generation, acquisition of diverse EDS data are first presented. Subsequently, various analysis approaches, including point analysis, grid analysis, and mapping analysis are discussed. This review then emphasizes the practical significance and potential value of SEM‐EDS analysis in addressing phase quantification challenges pertaining to cementitious systems. It is posited that the SEM‐EDS analysis holds the promise of becoming the characterization backbone for quantitative research on cementitious systems.
