Self-compacting concrete (SCC) and Steel fibre reinforced concrete (SFRC) have higher tensile strength capacity, limited crack width and higher post peak capacity, as well as easier construction handling. Thus SFRC allows for advanced and innovative

The production of ordinary Portland cement is associated with significant CO2 emissions. To limit these emissions, new binders are needed that can be efficiently substituted for cement. Alkali-activated slag composites are one such possible binder so
