Special Issue Information

Dear Colleagues,

This Special Issue focuses on the fundamental mechanisms and modification technologies of green low-carbon construction materials (e.g., recycled aggregate concrete, carbon-capture cementitious composites, collapsible loess embankment fillers, and bio-based geopolymers), covering microstructure evolution (e.g., hydration kinetics of low-clinker binders, montmorillonite-illite clay mineral transformations in loess, interfacial transition zone optimization), multi-field coupling effects (e.g., thermo-hydro-chemo-mechanical interactions in carbonation curing, unsaturated-seepage-collapse coupling of compacted loess), and performance enhancement methodologies (e.g., nano-silica reinforcement, bio-enzymatic stabilization of aeolian sand-loess mixtures, solid waste-derived cementitious materials). 

Given their critical role in global infrastructure decarbonization, the inherent heterogeneity and environmental sensitivity of these materials may induce engineering risks such as marine durability degradation, differential settlement of loess embankments, and cyclic load-induced cracking. Therefore, establishing constitutive models from material science perspectives (e.g., carbonation shrinkage prediction, collapsible deformation model of metastable loess, time-dependent rheology of geopolymer grouts) and developing robust modification strategies (e.g., graphene-enhanced conductive pavements, solid waste-cement modified loess fillers, enzymatic sediment stabilization) are imperative. 

The significance lies in achieving material–structure synergy for resilience (e.g., seismic-resistant fiber composites, gradation-optimized loess subgrades in arid regions) and enabling closed-loop resource utilization (e.g., CO₂-mineralized circular concrete, steel slag-fly ash stabilized loess for carbon-negative embankments). 

We welcome researchers, engineers, and industry professionals to contribute original research articles, reviews, and case studies that advance the science, engineering, and application of green low-carbon construction materials. Your contributions will help drive innovation in sustainable infrastructure and promote interdisciplinary collaboration toward a carbon-neutral future.

Bentonite materials are extensively used in cutoff walls at landfill sites. This study calculates the stress and permeability characteristics of bentonite materials using the piezocone penetration test (CPTU) and ABAQUS simulations. The lateral effective stress of bentonite materials is evaluated using arching models, lateral squeezing models, and a modified lateral squeezing model. Pore pressure dissipation types are categorized into standard and non-standard, with the coefficient of consolidation obtained using the half dissipation time of excess pore pressure (t50) method. In the standard dissipation type, the excess pore pressure gradually dissipates over time after the cone stops penetrating. In contrast, the non-standard dissipation type is characterized by an initial increase in pore pressure until it reaches a maximum value, followed by a decrease to hydrostatic pressure. Additionally, the pore pressure dissipation process in bentonite cutoff walls is recorded and analyzed over various time intervals. Finally, the relationship between hydraulic conductivity and t50 at landfill sites is established based on standard and non-standard dissipation types using CPTU and ABAQUS methods. The t50 method is used for the standard dissipation type, while a modified t50m method is used for the non-standard dissipation type from CPTU and a t50m method is used in the non-standard dissipation type from CPTU. The t50m is the modified value derived from t50. Cutoff walls made from bentonite materials offer the advantage of enhancing the isolation effects and meeting the design requirement of permeability (1.0 × 10−7 cm/s). Full article

Based on the G85 high-fill subgrade project in east Gansu Province, this study conducts one-dimensional compression tests in the laboratory on both disturbed and in situ-compacted loess. Through the combination of the test results of remolded soil, compaction standards for each layer of the subgrade fill are established, and quality inspections of the compacted subgrade are performed. The experimental results demonstrate that the compression deformation of remolded loess exhibits a positive correlation with compaction degree and a negative correlation with moisture content. Under constant compaction degree conditions, axial pressure and deformation follow a linear relationship, whereas under fixed conditions, the relationship adheres to a quadratic trend. Specimen void ratios show minimal variation within the 25–100 kPa stress range but undergo significant reduction between 100 and 400 kPa. Under an axial compressive load of 100–200 kPa, the compression coefficient at a height of 10 m within the subgrade ranges from 0.163 to 0.171 MPa−1. At a height of 6 m, it ranges from 0.177 to 0.183 MPa−1, and at 1 m, from 0.183 to 0.186 MPa−1. These values indicate that the compaction quality throughout the subgrade corresponds to a low compressibility level. However, the compaction quality near the slopes on both sides is slightly lower than that along the centerline of the subgrade. Overall, the compaction quality meets the required standards.
