Special Issue Information

Dear Colleagues,

Ultra-high-performance concretes (UHPC) and cementitious composites have emerged as revolutionary materials in the field of construction and engineering. These advanced materials offer exceptional mechanical properties, durability, functionality, and sustainability, opening up new frontiers in structural design and construction practices.

This Special Issue aims to bring together the latest research and developments in the field of ultra-high-performance concretes and cementitious composites. We invite contributions from researchers, engineers, and industry professionals to share their insights and findings on various aspects of these materials.

We welcome original research articles, review papers, and case studies that address the following topics:

  1. Development and characterization of ultra-high-performance concretes;
  2. Innovative cementitious composites for enhanced performance;
  3. Durability and long-term performance of UHPC and cementitious composites;
  4. Multifunctional and self-adaptive cementitious composites;
  5. Sustainable manufacturing and use of these materials;
  6. Applications of UHPC and cementitious composites in infrastructure projects;
  7. Numerical modeling and simulation of UHPC and cementitious composites;
  8. Experimental investigations and testing methods for these materials;
  9. New technologies and techniques for the production and processing of UHPC and cementitious composites.

Ultra-high-performance concrete incorporating coarse aggregates (UHPC-CA) exhibits pronounced multi-scale heterogeneity and staged damage evolution. However, existing single-scale reinforcement strategies often fail to address the complete micro-to-macro fracture process, leaving a critical research gap in achieving full-stage crack control. To address this, this study introduces a novel cross-scale toughening strategy using hybrid steel fibers (SF) and calcium carbonate whiskers (CCW), and decouples the coupled influences of water-to-binder (W/B) ratio, coarse aggregate (CA), and multi-scale fibers via an orthogonal design. Mechanical properties, fiber dispersion, and pore structure are jointly characterized to establish structure–property relationships. An optimal composition (W/B = 0.32, CA = 18%, SF = 2%, CCW = 1%) is identified, achieving a balanced enhancement of strength and ductility. Results indicate that matrix densification is primarily controlled by W/B via pore refinement, while mechanical performance is governed by the interplay between fiber spatial uniformity and interfacial integrity; the roles of CA and CCW are clearly stress-state dependent. Furthermore, a novel cross-scale synergistic mechanism is revealed, in which micro-scale CCW regulates microcrack initiation and stabilizes the pre-peak response, whereas macro-scale SF dominates post-peak behavior through crack bridging and pull-out energy dissipation. This sequential activation enables a full-stage enhancement of tensile performance, shifting failure from brittle localization to pseudo-ductile multiple cracking. The findings provide a correlative framework for tailoring UHPC-CA through multi-scale hybrid reinforcement. Full article
