Special Issue Information

Dear Colleagues,

High-performance concrete (HPC) is an advanced type of concrete distinguished by its superior mechanical properties, enhanced durability, and improved sustainability compared to its conventional form. With the increasing demands of HPC applied in modern infrastructure, this Special Issue explores the performance of HPC in terms of synergies between material innovation and structural health monitoring, aiming to address critical challenges in optimizing HPC’s mechanical properties, durability, and environmental sustainability while advancing real-time performance assessment and predictive maintenance frameworks. Overall, this Special Issue seeks to combine the benefits between new material design and advanced structural health monitoring technology, thereby fostering the development of resilient and intelligent concrete infrastructures.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: nanomaterials, engineered cementitious composites, AI-driven property prediction models, and integrated sensor networks for damage detection.

We look forward to receiving your contributions.

The incorporation of fly ash into concrete reduces cement consumption by 10–30%, lowers CO2 emissions by 30–50%, cuts costs by 15–25%, and enhances durability, thus reducing maintenance expenses. However, the predictive model for the elastic modulus of fly ash concrete subjected to calcium leaching is still lacking. Regarding the theoretical method, the content of calcium hydroxide and calcium silicate hydrate in fly ash–cement systems is quantitatively calculated according to the hydration reaction relationship between cement, fly ash, and water, and then the porosity of the fly ash–cement matrix and interface transition zone (ITZ) after calcium leaching can be obtained. Based on the theory of two-phase composite spheres and the non-uniform ITZ model, the prediction method for the elastic modulus of leached fly ash concrete can be constructed, which comprehensively considers key parameters such as fly ash content, non-uniform characteristics of the ITZ, and the water–binder ratio (w/b). Additionally, the corresponding experimental investigation is also designed to study the variation regulation of the leaching depth, leaching extent, and elastic modulus of fly ash concrete with leaching time. The prediction method for the elastic modulus of leached fly ash concrete is validated via self-designed experimental methods and third-party experiments. This study further delves into the specific effects of w/b, aggregate volume fraction (fa), fly ash content, and ITZ thickness (hITZ) on the elastic modulus of leached concrete (E). The research findings indicate that an appropriate amount of fly ash can effectively enhance the leaching resistance of concrete. For a leaching degree of 10.0%, 30.0%, and 50.0%, E at w/b = 0.40 exceeds that of w/b = 0.60 by 26.71%, 28.43%, and 30.28%, respectively; E at hITZ = 10 μm exceeds that of hITZ = 50 μm by 16.96%, 15.80%, and 15.11%, respectively; and E at fa = 65% is 39.82%, 43.15%, and 46.12% higher, respectively, than that of concrete with fa = 45%. Furthermore, a linear correlation exists between the elastic modulus and the degree of leaching. The prediction method for the elastic modulus offers a theoretical foundation for in-depth exploration of the durability of leached mineral admixture concrete and its scientific application in practical engineering.
