Special Issue Information

Dear Colleagues,

Nanomaterials, due to their unique physical and chemical properties, such as their high specific surface area, small size effect, and quantum effects, have become a research hotspot in the field of performance enhancement for building materials such as reinforced concrete. These materials show great potential in improving the mechanical properties, durability, and self-healing ability of concrete. In particular, the introduction of nanomaterials can significantly reduce the permeability of concrete, thereby enhancing its anti-corrosion performance, which is crucial for concrete structures used in marine and highly polluted environments. Although nanomaterials have shown positive effects in laboratory environments, they still face a series of challenges in practical engineering applications. These challenges include ensuring the uniform dispersion of nanomaterials in the concrete matrix, long-term performance stability, and considering environmental and health impacts. In addition, the unique optical properties of nanomaterials also provide possibilities for their application in the field of photoelectric cathodic protection. In view of this, the goal of this Special Issue is to compile and showcase the latest advances in the research and application of nanomaterials in building engineering. The Special Issue will contain a wide range of topics, including but not limited to the following:

  • Building materials;
  • Research and applications of nanomaterials in construction;
  • Functional coatings and modifications with nanomaterials;
  • The durability of reinforced concrete;
  • Nanomaterial-modified cement-based composite materials;
  • Applications of conductive polymers in building materials;
  • Nano repair materials;
  • The research and preparation of new nano building materials;
  • The research and application of corrosion inhibitors;
  • Performance evaluation and applications of nano-modified FRP bars.

Z-scheme Zn3In2S6/NiFe2O4 nanocomposites were prepared by electrospinning and hydrothermal methods, and their photocathodic protection performance was studied on 304 SS and Q235 CS in NaCl solution (3.5 wt.%). The two-dimensional Zn3In2S6 loaded on the one-dimensional NiFe2O4 resulted in faster electron migration and enhanced light absorption capability. Moreover, it had been observed through electrochemical testing that the assembly of Zn3In2S6/NiFe2O4 heterojunctions improves the efficacy of photocathodic protection. Following illumination, the self-corrosion potentials of 304 SS and Q235 CS coupled with Zn3In2S6/NiFe2O4 nanocomposites decreased by 1040 mV and 560 mV, and the photoinduced current densities were 1.2 times and 3.9 times greater than the value of Zn3In2S6. Furthermore, the mechanism of enhanced photocathodic protection performance for Zn3In2S6/NiFe2O4 heterojunctions was systematically discussed. XPS and ESR analysis indicated that Zn3In2S6/NiFe2O4 composites follow the Z-scheme electron migration path and retain the stronger reduction and oxidation capacity of Zn3In2S6/NiFe2O4. Therefore, the Z-scheme heterostructures are responsible for the realization of cathodic protection for carbon steel. Full article

With the continuous improvement in technology, the construction industry is constantly advancing. Traditional concrete can no longer meet modern market demands, making research on new types of concrete imperative. This study reviews the application of common nanomaterials in concrete and their impact on concrete performance. It provides a detailed explanation of the characteristics of three common nanomaterials: nano-silica, nano-calcium carbonate, and carbon nanotubes. This study analyzes how these materials improve the microstructure, accelerate hydration reactions, and enhance interfacial transition zones, thereby enhancing the mechanical properties, durability, and workability of concrete. For conventional engineering projects, nano-calcium carbonate is the preferred choice owing to its low cost and its capacity to improve workability and early-age strength. For high-strength and durable structures, nano-silica is selected due to its high specific surface area (ranging from 100 to 800 m2/g) and its superior compactness and impermeability. In the context of intelligent buildings, carbon nanotubes are the most suitable option because of their exceptional thermal conductivity and electrical conductivity (with axial thermal conductivity reaching 2000–6000 W/m*K and electrical conductivity ranging from 103 to 106 S/cm). However, it should be noted that carbon nanotubes are the most expensive among the three materials. Additionally, this study discusses the issues and challenges currently faced by the application of nanomaterials in concrete and looks ahead to future research directions, aiming to provide a reference for further research and engineering applications of nanomaterials in the field of concrete.
