He, S. (author), Mustafa, S. (author), Chang, Z. (author), Liang, M. (author), Schlangen, E. (author), Lukovic, M. (author)In the current study, experiments and numerical simulations were carried out to investigate the cracking behavior of reinforced concrete beams consisting of a very thin layer (i.e., 1 cm in thickness) of SHCC in the concrete cover, tension zone. A novel type of SHCC/concrete interface that features a weakened chemical adhesion but an enhanced...journal article 2023

He, S. (author), Wan, Z. (author), Chen, Y. (author), Jonkers, H.M. (author), Schlangen, E. (author)The current study investigates short-term and long-term crack-healing behaviour of mortars embedded with bacteria-based poly-lactic acid (PLA) capsules under both ideal and realistic environmental conditions. Two sets of specimens were prepared and subjected to different healing regimes, with the first set kept in a mist room for varying...journal article 2023

He, S. (author), Zhang, Shizhe (author), Lukovic, M. (author), Schlangen, E. (author)Strain hardening cementitious composite (SHCC) is a special class of ultra-ductile material which has autogenous self-healing capability due to its intrinsic tight crack widths. To further improve its healing ability, healing agent (HA) can be incorporated in SHCC, enabling it also the autonomous self-healing mechanism. In this study, the...journal article 2022
