What is Cracking Behaviour of Strain-Hardening Cementitious Composites (SHCC) Under Practical Creep Conditions about?

Strain-Hardening Cementitious Composites (SHCC) have become increasingly popular as a material which could be adopted for enhancing the durability of structures. Studies have shown that the cracks formed during shortterm tensile loading in SHCCs can be controlled in the range of 50-100 μm as compared to conventional reinforced concrete, where cracks are designed to be around 200-300 μm at serviceability state. Thereby, applying SHCC as an additional protective layer (e.g. permanent formwork) on the concrete tensile face can effectively control the ingress of water and harmful chemicals due to the fine crack size, thus improving the durability of the structure. Although the crack widths are small under short-term loading, imposing a constant sustained load on SHCC over a longer period has shown to increase the crack size beyond acceptable levels (to over 200 μm). In real structures, however, the deformation is limited by design as well as load sharing between structural elements, therefore the crack patterns in such cases will follow a different propagation mechanism to that under constant loading tests. Specifically, for a reinforced concrete member with a SHCC layer on the surface
