Special Issue Information

Dear Colleagues,

Under the dual-carbon background, the consolidation of existing damaged concrete structures with high-performance building life-prolonging materials is cost-effective and environment-friendly rather than destroying reconstruction. It is essential to develop building life-prolonging materials to possess high toughness, good thin-layer anti-cracking, low shrinkage, sufficient interface bonding, and bonding durability with old concrete substrate, along with the corresponding on-site consolidation and protection-serving behaviors. Building life-prolonging materials can be generally divided into inorganic, organic, and hybrid cementitious systems. Inorganic building life-prolonging materials can provide sufficient durability with concrete substrate, such as Portland cement, sulphoaluminate cement, magnesium phosphate cement, alkali-activated geopolymers, etc., whereas the organic building life-prolonging materials can bring forth adequate interface bonding, such as acrylate polymers, polyvinyl alcohol, styrene butadiene rubber polymers, ethylene vinyl acetate polymers, or latex, etc. Actually, building life-prolonging materials with hybrid cementitious systems can combine the two advantages above, but should be mix-proportion designed and carefully prepared to finally achieve the compromised and expected properties, which is worth extensive study and systematic exploration.

Organic polymer introduction effectively enhances the toughness, bond strength, and durability of ordinary cement-based materials, and is often used for concrete repair and reinforcement. However, the entrained air effect simultaneously induced by polymer and the inhibitory action on cement hydration kinetics often lead to degradation in mechanical performances of polymer-modified cement-based composite (PMC). Nanomaterials provide unique advantages in enhancing the properties of PMC due to their characteristic ultrahigh specific surface area, quantum effects, and interface modulation capabilities. This review systematically examines recent advances in nano-reinforced PMC (NPMC), elucidating their synergistic optimization mechanisms. The synergistic effects of nanomaterials—nano-nucleation, pore-filling, and templating mechanisms—refine the microstructure, significantly enhancing the mechanical strength, impermeability, and erosion resistance of NPMC. Furthermore, nanomaterials establish interpenetrating network structures (A composite structure composed of polymer networks and other materials interwoven with each other) with polymer cured film (The film formed after the polymer loses water), enhancing load-transfer efficiency through physical and chemical action while optimizing dispersion and compatibility of nanomaterials and polymers. By systematically analyzing the synergy among nanomaterials, polymer, and cement matrix, this work provides valuable insights for advancing high-performance repair materials. Full article
