Special Issue Information

Dear Colleagues,

High-performance concrete is one of the indispensable materials in modern urban construction. It bears the important mission of promoting the urbanization process. Its quality is directly related to the quality of construction projects and is the fundamental guarantee for ensuring the quality of projects. In addition, low carbon and environmental protection have become new requirements for the concrete industry in modern society. Therefore, we need to continuously explore low-carbon high-performance concrete to better achieve sustainability and cost-effectiveness while meeting basic performance requirements. This Special Issue aims to deeply explore the performance change mechanism of building materials, stimulate innovation, promote the development of low-carbon concrete technology and promote the sustainable development of the construction industry. The topics for this Special Issue include (but are not limited to) the following:

  • Low-carbon concrete;
  • High-performance concrete;
  • Sustainable building materials;
  • Mineral admixtures;
  • Industrial waste and by-products;
  • Alternative cementitious materials;
  • Solid waste-recycled concrete;
  • Carbonation;
  • Carbon dioxide capture, utilization and storage;
  • Life cycle sustainability.

With the rise in the marine industry and marine tourism, coral powder is increasingly used to make concrete for marine islands. This study proposes a three-parameter hydration model and a hydration kinetic model to predict the performance of coral powder concrete based on previous experimental data. The process of the proposed prediction model is as follows: 1. The input parameters of the three-parameter hydration model are calibrated for the first 7 days using the cumulative hydration heat per gram of cement. The maximum cumulative hydration heat (455.87 J/g cement) and the shape coefficient (−0.87) remain constant. In this study, the hydration rate coefficients for 0%, 10%, and 20% coral powder were 6.91, 6.19, and 5.55, respectively, showing decreases of 10.41% and 19.68% compared with the specimens without coral powder. 2. At 28 days, the cumulative heat release values per gram of cement for 0%, 10%, and 20% coral powder were 389.77, 395.69, and 401.62 J/g, showing increases of 1.52% and 3.04% for the specimens containing 10% and 20% coral powder, respectively. Meanwhile, the hydration degrees for 0%, 10%, and 20% coral powder were 0.855, 0.868, and 0.881, respectively, showing increases of 1.52% and 3.04%. Furthermore, the cumulative heat release values per gram of binder were 389.77, 356.12, and 321.29 J/g, showing decreases of 8.63% and 17.56% for specimens containing 10% and 20% coral powder, respectively. 3. Properties such as compressive strength, ultrasonic pulse velocity (UPV), and surface electrical resistivity were evaluated using the power function and the cumulative hydration heat per gram of binder. 4. At 28 days, the chemically bound water contents for samples with 0%, 10%, and 20% coral powder were 0.2402, 0.2197, and 0.1981 g/g binder, respectively. Moreover, the calcium hydroxide contents were 0.1848, 0.1690, and 0.1524 g/g binder, showing reductions of 8.53% and 17.52% in bound water and 8.54% and 17.53% in calcium hydroxide. 5. A hydration kinetic model is proposed, which can distinguish between the dilution effect and the nucleation effect of coral powder, unlike the three-parameter model, which cannot distinguish between the two effects. Furthermore, the input parameters of the hydration kinetic model remain unchanged for different mixtures, while the input parameters of the three-parameter model must be varied among mixtures. Parameter analysis of the hydration kinetic model indicated that a low water–binder ratio and a high coral powder substitution rate significantly improve the relative reaction level of cement.
