• Mechanical responses and microscopic mechanisms of NS-PVA-ECC under static and dynamic loads across a wide temperature range are studied. • Both the static and dynamic compressive strength properties of NS-PVA-ECC are regulated nonlinearly with temperature. • Incorporation of nano-SiO 2 (NS) in PVA-ECC consistently improves the matrix densification and promotes the sustained improvement of the macroscopic compressive strength.
