Abstract

The chapter delves into the limitations of conventional cementitious matrices and introduces strain-hardening cementitious composites (SHCC) as a solution. It then focuses on the use of limestone calcined clay cement (LC3) as a more sustainable binder. The study investigates the effectiveness of polydopamine and chitosan as bio-inspired adhesion promoters for UHMWPE fibers, aiming to improve their interaction with the cement matrix. Through a layer-by-layer coating technique, the authors demonstrate significant enhancements in fiber-matrix adhesion, as evidenced by increased interfacial shear strength and pullout energy. The chapter concludes with a discussion of the results and potential future research directions, making it a valuable resource for professionals seeking to advance the field of fiber-reinforced cement composites.
