N2 - Basic oxygen furnace (BOF) slag is an industrial by-product of the steel industry and has recently been investigated intensively for high-end applications other than road load and land fill. However, to be applied as a high-end raw material BOF slag lacks a quick and simple quantitative phase analysis method compared to the Bogue approach applied to ordinary Portland cement. This study presents a method to calculate the main phases of BOF slag (C2S, C2(A,F), magnetite (Ff), RO-Phase and f-C) based on chemical composition. A quantitative model assessment was performed in order to further improve the model and two approaches were used to validate the Bogue BOF slag model. One approach compared the calculated chemical composition of phases with real data the second one evaluated whether the Bogue BOF slag model gives comparable quantitative model assessment measures compared to the classical cement Bogue approach. Both approaches validated the proposed final model.
