Special Issue Information

Dear Colleagues,

With the increasing focus on carbon neutrality and climate change, the global demand for sustainable construction has grown. In the field of construction materials, many innovations have been devised in the development of advanced sustainable materials, such as ultra-high-performance concrete, recycled concrete, carbon-negative concrete, and alkali-activated concrete. Additionally, new construction technologies, such as 3D-printed concrete and prefabricated and prefinished volumetric construction, have also been developed. These innovations have enabled constructions to be more durable, sustainable, resilient, and energy efficient. The main purpose of this Special Issue is to introduce the latest developments and advances in sustainable construction materials. It will provide a platform for exchanging ideas, disseminating significant advances, and sharing concepts and visions regarding the design, preparation, evaluation, and performance optimization of new concrete materials. This Special Issue also welcomes contributions from academics and practitioners on the innovations and applications of new construction materials. Original research papers, case studies, and review papers are all welcome.

As an environmentally friendly pavement material, porous concrete in seasonal frozen region is often subjected to repeated loads and freeze-thaw cycles. Therefore, the fatigue property of porous concrete under freeze-thaw is extremely important. However, few researches have been reported on the topic. Based on this background, this paper investigates the flexural fatigue property of ground tire rubber/silica fume composite modified porous concrete (GTR/SF-PC) with experimental and mathematical statistical methods. The flexural fatigue life of GTR/SF-PC under different freeze-thaw cycles (0, 15, 30) was tested with three-point flexural fatigue experiment at four stress levels (0.70, 0.75, 0.80, 0.85). Kaplan Meier survival analysis and Weibull model were adopted to analyze and characterize the flexural fatigue life. The fatigue life equations of GTR/SF-PC under different freeze-thaw cycles were established. The results indicate that, duo to the addition of ground tire rubber and silica fume, the static flexural strength of GTR/SF-PC is not significantly affected by freeze-thaw cycles. The flexural fatigue property of GTR/SF-PC is gradually deteriorated under the action of freeze-thaw cycles. Compared with 0 freeze-thaw cycles, the average flexural fatigue life of GTR/SF-PC decreases about 15% and the fatigue failure rate increases about 50% after 30 freeze-thaw cycles, respectively. The fatigue equations with different reliabilities of GTR/SF-PC show that the reliability is inversely proportional to fatigue life, therefore, the appropriate fatigue equation considering freeze-thaw effect is necessary for fatigue design of porous concrete.
