Special Issue Information

Dear Colleagues,

The urgent global need for sustainable construction solutions is driving a paradigm shift in how we design and manufacture cementitious materials. As the construction industry grapples with mounting environmental pressures, including resource depletion, construction and demolition waste, and rising carbon emissions, replacing conventional aggregates with recycled solid waste materials presents a promising path toward greener and more resilient infrastructure.

This Special Issue, titled “Eco-Friendly and Low-Carbon Cement-Based Materials”, aims to highlight the latest scientific and technological advancements in the development, performance assessment, and application of sustainable cement-based composites that incorporate recycled solid materials such as construction and demolition waste, industrial by-products, and other alternative aggregates. By focusing on circular economic principles, this Issue seeks to foster innovation in material reuse, resource efficiency, and low-carbon cementitious technologies.

We invite original research and comprehensive reviews that explore the integration of recycled solid aggregates into cement-based systems, with particular attention to their influence on mechanical behavior, durability, thermal performance, and long-term sustainability. Contributions that bridge laboratory research with real-world applications, especially in challenging environments such as marine, coastal, and underground infrastructures, are especially welcome.

Topics of interest include, but are not limited to, the following:

  • Characterization and processing of recycled aggregates for use in concrete;
  • Durability, permeability, and mechanical performance of recycled-aggregate concrete;
  • Thermal and energy performance of concrete with recycled solid materials;
  • Pre-treatment methods for recycled aggregates and their effects on concrete behavior;
  • Compatibility of recycled aggregates with supplementary cementitious materials (SCMs);
  • Multi-functional concrete incorporating recycled materials and phase change materials (PCMs);
  • Lifecycle assessment (LCA) and carbon footprint analysis of green concrete;
  • Innovative mix design approaches for structural and non-structural applications;
  • Recycled aggregates in self-compacting concrete, ECC, and UHPC systems;
  • Performance of recycled-aggregate concrete under harsh or aggressive exposures.

This Special Issue aligns with the journal’s mission to promote sustainable materials, circularity, and innovation in civil and environmental engineering. We look forward to receiving your valuable contributions that will help advance the science and practice of green construction.

A mesoscale model for chloride diffusion in reinforced concrete was established by considering the blocking effect of reinforcing steel. This model improved the accuracy of chloride concentration prediction and enhanced the reliability of durability-based service-life assessment. First, a series of chloride transport experiments under wetting–drying cycles was carried out on reinforced concrete specimens. These experiments were used to evaluate the effects of exposure condition, rebar blocking, and concrete compressive strength on chloride transport. Then, a mesoscale chloride diffusion model including the rebar-induced blocking effect was developed and validated. Finally, a sensitivity analysis of the key parameters was conducted. The results showed that, compared with concrete without longitudinal reinforcement, wetting–drying cycles had a stronger influence on reinforced concrete with longitudinal bars. The enhancing effect of wetting–drying cycles on chloride ingress was the strongest, followed by compressive strength and then the rebar-induced blocking effect, although the latter was still non-negligible. As the rebar diameter increased, the peak chloride concentration increased, and the chloride concentration around the aggregates also increased more rapidly. Full article

Rapid-hardening concrete is widely used for rapid repairs but can suffer from accelerated hydration, shrinkage-related cracking, and durability concerns. This study evaluates the feasibility of replacing cement with OLED waste glass powder (0–30%) in CSA-type rapid-hardening concrete as a low-impact repair material. Mixtures were prepared at a constant binder content (400 kg/m3) and water-to-binder ratio (0.425), and fresh properties (slump, air content, setting time) and mechanical performance (compressive and bond strength) were tested from 4 h to 56 d. Mercury intrusion porosimetry (MIP) and TG/DTG were additionally used to interpret changes in pore structure and hydration-related thermal indices. Increasing glass powder replacement improved workability but delayed setting. A 10% replacement (O-GP10) maintained 4 h compressive strength and showed slightly higher long-term strength and consistently higher long-term bond strength than the control, whereas 20–30% replacement caused pronounced strength loss due to dilution. MIP results indicated that O-GP10 suppressed large pores (>0.1 μm) and promoted a refined pore structure dominated by finer pores. TG/DTG trends were interpreted using temperature windows as comparative indicators, suggesting age-dependent bound-water development and a reduced apparent contribution in the Al-bearing-hydrate-related region for O-GP10. Overall, roughly 10% OLED waste glass powder is suggested for CSA rapid-hardening concrete to ensure early functioning while enhancing long-term bonding and microstructural stability. Full article
