Microstructure Evolution of Cementitious Matrices Utilising Graphite Mine Tailing as Supplementary Cementitious Materialsecondary hydration. This also results in more compact matrices at the later ages. These findings together with the findings of FTIR and XRD studies give an insight into the hydration of cementitious pastes containing mine tailing.

RECUR

Reuse of EAF Slag as Aggregates in Structural Concretes concrete mixtures have been produced and in two of which the natural fine and coarse aggregates has been replaced by two different percentage of EAF slag, 25 and 50%. Once the mechanical characterisation of the mixtures had been carried out, they were then used to produce full-scale beams in order to study both flexural and shear behaviour.

The Impact of Carbonated Fine Recycled Aggregates on Sulfate and Acid Attack of Mortarns. This research offers a good understanding of long-term performance implications. By contributing to discussions on sustainable construction practices, it underscores the necessity for further exploration in this promising field.

Thermally Treated Residues and By-Products as Components of Waste-Based Alkali-Activated Materialsaimed during the upcycling process. Further research has also been identified as necessary to improve our understanding of chemical and mineralogical boundary conditions for using upcycled slags as AAM binder components.

On the Prediction of Strength and Optimum Mix-Designs of Mineral-Waste-Based Alkali-Activated Materialswing interactive variables were considered: (i) waste content, (ii) compressive strength and (iii) water/binder ratio. Future focus is given on the evaluation of more complex systems containing a variety waste sources.
