Sustainable magnesium phosphate micromortars formulated with PAVAL® alumina by-product as micro-aggregate

Can Tundish Deskulling Waste Be Used as a Magnesium Oxide Source to Develop Magnesium Phosphate Cement?

“…However, the increase is more pronounced in the FS test compared to the CS test, which can be attributed to the nature of each test and the porosity of the samples. These findings are consistent with previously reported mechanical results for MPCs formulated with similar waste and/or by-products [25]. Other studies with different by-products of MgO, such as low-grade magnesium oxide (LG-MgO), achieved similar responses with same specimen size.…”

“…It should be noted that the concentrations of all the other metal(oid)s are classified as inert. The trend of increasing concentrations of Mo, Sb, and Se in relation to the raw material has been also observed in other studies involving MPCs developed with various waste and industrial by-products, including LG-MgO [25]. In the coming future, research should be conducted to investigate the internal reaction of these cements and determine the chemical response to this trend.…”
