Special Issue Information

Dear Colleagues,

With rapid economic development and urbanization, the widespread use of concrete has led to significant carbon emissions. To address this challenge, this Special Issue, titled "Low-Carbon Concrete from Different Solid Waste Sources", aims to bring together researchers, experts, and practitioners to discuss the latest research findings on mechanical properties, durability, microstructure, and environmental impact. In addition, we encourage the exploration of potential solutions for low-carbon concrete production using solid waste materials.

The Special Issue will cover, but is not limited to, the following:

  • Low-carbon UHPC;
  • Multi-physics deterioration modeling for reinforced concrete structures;
  • FRP-reinforced concrete structures;
  • Modular construction;
  • The preparation process of low-carbon concrete from solid waste sources and its effects on mechanical properties, durability, and environmental impact;
  • The effects mechanisms of solid waste admixture on concrete microstructure;
  • The current status and prospects of solid waste applications in low-carbon concrete;
  • The technical challenges and policy recommendations for the resource utilization of solid waste;
  • 3D printing concrete construction virtual simulation and numerical simulation;
  • The application of multi-scale stochastic finite element in isogeometric analysis;
  • Computer-aided design and finite element software development.

For concrete structures in offshore areas, chloride ion erosion is one of the main factors affecting durability. It is crucial to evaluate the chloride ion permeability resistance of concrete structures. In this paper, a finite element simulation of the chloride ion diffusion process in concrete is conducted. A mass diffusion finite element model based on a random aggregate approach is established to investigate the influences of an aggregate, the interface transition zone, and micro-cracks on the chloride ion diffusion coefficients in concrete. The results show that the mass diffusion finite element analysis based on the exponential function model and the power function model can effectively simulate the chloride ion diffusion process in concrete. In addition, the data reveal that volume fraction and distribution aggregates considerably affect chloride ion diffusivity in concrete. Also, the interface transition zone significantly accelerates chloride ion diffusion in concrete. Moreover, this acceleration effect exceeds the barrier effect of an aggregate. Full article
