Functionalization of basic oxygen steelmaking slag

A High Efficiency Approach to Carbon Capture & Permanent Sequestration Through Mineralization

“…In traditional processes aggregate is blended with asphalt, but because of the hydrophilic nature of natural aggregate surfaces it is generally required that a solvent is added to facilitate a uniform blend. Researchers at the Central Science Research Institute (CSRI) and Central Road Research Institute (CSRI) in India and in our laboratories (Fisher et al, 2023) have shown that it is possible to make slag hydrophobic through chemical reaction, after which blending with asphalt becomes possible without additional additives. Importantly, the aggregate produced by the ZAP-C 3 process from BOS slag is shown to be hydrophobic and as such is ideal for road construction.…”

The Use of Steelmaking Slags in Land and Marine Applications

“…The method used for the BOS slag synthesis was previously reported in Chapter 5 as well as in several scientific publications (Fisher & Barron, 2023;Hill et al, 2019;S. M. Lee et al, 2018).…”

“…The similarity between lanolin and steric acid is reasonable given that lanolin is a sterol ester (even though it was traditionally called "wool fat") of various C12-C24 carboxylic acids. Thus, lanolin, a side product from wool production, has been shown to act as a "hidden" source of long-chain carboxylic acids, c.f., lauric acid (Fisher & Barron, 2023).…”

“…The work presented in Chapter 5 was previously presented at the 8 th Brunei International Conference on Engineering and Technology 2021. The conference proceeding were published online as of 10/1/2023 (Fisher & Barron, 2023) . There are further graphs and images from the work in Appendix B.…”
