Abstract (EN):
The aim of this research was to investigate the influence of cracking on water transport by
capillary suction in UHPFRC. Specimens were firstly pre-loaded under four-point bending up
to a wide range of pre-defined crack open displacement. Crack pattern created was
characterized (width, number of cracks) before capillarity testing. Test results showed that
micro cracks induced by previous loading significantly increased the sorptivity comparing
with non-cracked specimens. However, increasing the damage (COD of 200 up to 400 µm),
did not significantly compromise the absorption capillary suction of UHPFRC, as compared
to good quality conventional concrete or engineered cementitious composites (ECC).
