The micromechanical signature of high-volume natural pozzolan concrete by combined statistical nanoindentation and SEM-EDS analyses

Although concrete sustainability can be remarkably improved by replacing high amounts of Portland cement clinker with supplementary cementitious materials (SCMs), this approach is far from being fully exploited. To compete with conventional concrete, a better understanding of low-cement concrete is needed regarding both microstructural features responsible for mechanical performance and key parameters for robust mix design. In particular, this...
