Transport of water through strain-hardening cement-based composite (SHCC) applied on top of cracked reinforced concrete slabs with and without hydrophobization of cracks – Investigation by neutron radiography

•Capillary suction and drying kinetics of cracked RC/SHCC systems are studied.•Water migration was non-destructively visualized and quantified by neutron radiography.•Hydrophobization inhibits moisture ingress into cracks in the RC substrate efficiently.•Crack widths affect drying kinetics substanti...
