Rapid industrialization and reconstruction efforts resulting from various wars have produced significant pollution and overconsumption of natural resources causing significant global climate anomalies, especially within the concrete industry. As such, the last few decades have called for increasing demand in both eco-friendly concrete developments and concrete for protective structure implementation. This study aims to investigate avenues for the development of an eco-friendlier HSC for use in both general and protective applications. Two methods will be explored, firstly, the heavy reduction of cement targeting a minimum of 40% and maximum of 80% cement replacement when compared to a reference mix that is comparatively low in cement to other typical high-strength concretes. And secondly, the application of functionally graded concrete where the newly developed HSC will be placed in the most functional regions of the member assessing flexural capacity. Research findings detail small or large strength reductions in the HSC material up to 80% replacement compared to the reference material. HSC with 80% replacement of cement detailed an early strength of 41 MPa, and 60% replacement detailed strengths of up to 75 MPa when reinforced with 2.0 wt% of arc steel fibers, exceeding the target strength of 70 MPa. Furthermore, for FGC specimens, early age strength development under normal curing regimes led to reduced strength compared to HSC specimens, due to strength development in the NC region. However, steam cured specimens and 28-day strength specimens detailed near similar strengths to similar mono- HSC specimens. These materials show suitability for use in general construction and the protective construction industry. Reduced material emissions, and use of zero(low)-cost by products will significantly reduce the financial and environmental impact of restoration as well as strengthening of existing structures. Further supporting construction and recovery efforts pre- and post-destruction event, through reduced economic and environmental impacts.
