Special Issue Information

Dear Colleagues,

Corrosion of steel reinforcement remains the predominant threat to the longevity of reinforced concrete infrastructure globally. This Special Issue of Buildings aims to advance our understanding of rebar corrosion, ranging from the fundamental breakdown of steel passivation to complex electrochemical mechanisms while showcasing the latest strategies for enhancing structural resilience.

Contributions should explore the multi-faceted approaches to combat rebar corrosion. These include advanced surface protection technologies such as novel coating systems and sustainable cathodic protection methods, alongside the effective use of migrating and embedded corrosion inhibitors. Complementing these defensive measures, this Special Issue will explore proactive material-level innovations designed to improve the intrinsic properties of concrete. These encompass the application of internal curing materials to mitigate early-age cracking and the development of advanced self-healing materials for autonomic damage repair.

By integrating studies on materials science, electrochemical principles, and structural performance, this Special Issue will provide a comprehensive resource for understanding and mitigating the multifaceted deterioration of concrete. This Special Issue aims to bridge the gap between laboratory research and practical application, offering valuable insights for researchers and engineers dedicated to designing more durable, sustainable, and intelligent concrete structures for the future. Submissions may explore a wide range of topics, including, but not limited to, the following aspects: rebar corrosion and protection; advanced coating technology; durability enhancement; cement-based composites; self-healing materials; internal curing technology; corrosion inhibitor application; novel repair materials; or concrete deterioration mechanisms.

Recycled concrete powder (RCP) utilization as an auxiliary cementitious material absorbs construction waste and promotes low-carbon transition in construction by replacing high-carbon materials. This study optimized RCP’s particle size and amorphous SiO2 content through physical activation, systematically investigating its effects on alkali-activated cementitious materials (AACMs). The results demonstrated that 20% activated RCP enhanced compressive strength by 9% (34.2 MPa), only 12.7% lower than that of the reference samples. Hydration analysis revealed activated RCP delayed exothermic peaks but increased total heat via active particles. Life-cycle assessment showed substituting 20% ground granulated blast-furnace slag (GGBS)/fly ash (FA) with RCP reduced carbon emissions from 169.3 to 165.9 kg CO2-e/ton (−2.1%). Although activation slightly raised emissions to 166.6 kg CO2-e/ton, RCP’s carbon contribution remained at 9% versus GGBS’s 83% dominance. Crucially, the activation’s 0.7 kg CO2-e/ton increase was offset by 4.7 kg CO2-e/ton reductions from material substitution and waste recycling benefits, confirming its net carbon-neutral potential.
