Special Issue Information

Dear Colleagues,

As is well known, reinforced concrete (RC) structures are widely used in civil engineering. With the increase in service time, the bearing performance of RC structures will be affected by many factors, such as corrosion, fatigue damage, etc. In addition, disasters such as earthquakes and fires can significantly weaken the service performance of RC structures. In order to accurately evaluate the service performance of RC structures, it is necessary to conduct comprehensive research on their durability. At present, many research studies have been carried out to reveal the durability of RC structures under various adverse factors such as high temperature, corrosion, carbonization, fatigue damage, etc. However, as human exploration space gradually expands from land to sea, the harsher service environment has an adverse impact on the durability of RC structures. This Special Issue aims to publish research papers and reviews on the evolution of the service performance and durability of RC structures under the influence of multiple factors.

In this paper, the early drying shrinkage coefficients of different hydraulic cement mortars are calibrated through laboratory experiments for moderate-heat Portland cement (MHPC) and low-heat Portland cement (LHPC). By developing an improved mesoscale modeling approach, a 3D highly detailed simulation of concrete was generated, which incorporates the phases of mortar, aggregates, and interfacial transition zone (ITZ). The simulation result is in good agreement with the concrete early drying shrinkage experiment, exhibiting an error of less than 4.99% after 28 days. Subsequently, the mesoscale model is employed to explain the influence of the ambient humidity, cement type, and aggregate volume ratio on the early drying shrinkage performance of concrete. The results show that the early drying shrinkage coefficient of the LHPC is approximately 82% of the MHPC. Additionally, the depth of ambient humidity influence is about 15 mm from the concrete surface after 28 days. The early drying shrinkage can be controlled by increasing ambient humidity via the LHPC or raising the aggregate volume ratio. The mass-loss rate of concrete decreases as the ambient humidity or aggregate volume ratio increases during the process of drying shrinkage. Furthermore, the results quantify the influence patterns of various factors on drying shrinkage, thereby facilitating their application in assessing the cracking time induced by early drying shrinkage in roller-compacted concrete (RCC) dams. This provides theoretical guidance for crack prevention in concrete structures and aids in developing strategies for the construction of crack-free dams. Full article
