Special Issue Information

Dear Colleagues,

The Special Issue, entitled "Industrial Solid Wastes for Construction and Building Materials", covers the fields of environmental and materials science and engineering. It will focus on the utilization of industrial solid waste in construction and building materials, present technologies that aim to reduce the impact of waste on the environment, and assess the sustainable use of waste in society. It will also address the preparation of building materials using industrial solid waste as the main raw material, as well as the development of green production processes that can be employed in the fields of construction, environmental protection, energy storage, etc.

The scope of this Special Issue includes, but is not limited to, the following topics:

  • Cement, concrete, ceramics, bituminous materials, wall materials, road materials, bricks, mortars, additives, recycled materials, composite materials, and new building materials;
  • Porous materials (light weight, sound insulation, and heat insulation);
  • Energy storage materials;
  • The application of intellectualization in solid-waste-based building materials;
  • The application of industrial solid waste in building materials;
  • The application of advanced methods and techniques in solid-waste-based building materials;
  • The life cycle assessment of building materials.

Comprehensive Study on Design Optimization and Retardation Mechanism of SS-GGBS-FA Ternary Geopolymer Mortar

A ternary geopolymer mortar (TGM) was synthesized using steel slag (SS), granulated blast furnace slag (GGBS), and fly ash (FA) as raw materials. The effect of the SS content (0–60%) and the GGBS/FA mass ratio (5:1 to 1:5) on the TGM’s setting time was studied. To address the issue of rapid setting, the impact of different mixing methods ((A) dry mixing, (B) pre-dissolution, and (C) pre-coating) and dosages of BaCl2 on the setting and hardening properties of TGM was further explored. The hydration product evolution and microstructural characteristics were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectrometry (EDS), with an in-depth analysis of the retarding mechanism of BaCl2. The results indicate that, as the steel slag content increases, the setting time of TGM significantly shortens. The setting time decreases slightly with an increase in the GGBS/FA mass ratio. The mixing method influences the retarding effect of BaCl2, with the C method showing significant advantages over both the A and B methods. Under the C mixing method, BaCl2 consumes the alkaline components (SiO32−) in the alkaline activator and forms a BaSiO3 coating layer on the precursor surface, which further delays the hydration process of the precursor particles. This study provides a promising approach for the high-value utilization of multi-source solid waste and suggests that future research should focus on large-scale application strategies and long-term performance evaluation to support its practical use in sustainable construction.
