Special Issue Information

Dear Colleagues,

In recent years, there has been a significant global interest in the concept of eco-friendly materials. The vast use of cementitious materials brings a heavy burden on the environment, especially, as they contribute to 8% of the global carbon dioxide emission through their production, transportation and use. This Special Issue, Properties, Structures and Practical Applications of Eco-Friendly Cementitious Materials (Eco-CM), delves into an in-depth exploration of the material properties, structural modifications and practical applications of eco-friendly cementitious materials, involving ultra-high performance concrete (UHPC), engineered cementitious composite (ECC), fiber-reinforced concrete (FRC), self-compacting concrete, self-healing concrete, nano-engineered concrete, alkali-activated concrete, etc. Eco-CM invites submissions on studies related to the comprehensively analysis of the various characteristics exhibited by these materials (e.g., their mechanical, thermal and durability properties). We encourage investigations aimed at revealing the potential of modifying the structural composition of cementitious materials for enhancing their performance and adaptability. Moreover, we welcome studies delving into the practical applications of these materials in diverse fields, such as construction, infrastructure and sustainable development. By shedding light on the intricate interplay between material properties, their structural modifications and their practical applications, Eco-CM aims to offer valuable insights to researchers, engineers and practitioners that seek to optimize and innovate cementitious materials.

The use of seawater sea sand concrete (SSSC) and fiber-reinforced polymer (FRP) has broad application prospect in island and coastal areas. However, the elastic modulus of FRP reinforcement is obviously lower than that of ordinary steel reinforcement, and the properties of SSSC are different from that of ordinary concrete, which results in a limit in the bearing capacity and stiffness of structures. In order to improve the flexural performance of FRP-reinforced SSSC beams, a novel SSSC beam with built-in glass FRP (GFRP) tubes was proposed in this study. Referring to many large-scale beam experiments, one specimen was used for one situation to illustrate the study considering costs and feasibility. Firstly, flexural performance tests of SSSC beams with GFRP tubes were conducted. Then, the effects of the GFRP tubes’ height, the strength grades of concrete inside and outside the GFRP tubes, and the GFRP reinforcement ratio on the flexural behaviors of the beams were investigated. In addition, the concept of capacity reserve was proposed to assess the ductility of the beams, and the interaction between the concrete outside the GFRP tube, the GFRP tube and concrete inside the tube was discussed. Finally, the formulas for the normal section bearing capacity of beams with built-in GFRP tubes were derived and verified. Compared to the beam without GFRP tubes, under the same conditions, the ultimate bearing capacities of the SSSC beam with 80 mm, 100, and 200 mm height GFRP tubes were increased by 17.67 kN, 24.52 kN, and 144.42 kN, respectively.

Distortion deformation usually imposes a potential threat to bridge safety. In order to comprehensively understand the distortion effect on thin-walled ultra-high performance concrete (UHPC) box girders, an innovative approach encompassing the governing distortion differential equation is introduced in this study based on the general definition of distortion angle within the cross-section plane. The analytical results obtained from the proposed method are in accordance with those obtained from the energy method, and exhibit favorable agreement with experimental findings documented in the existing literature. Furthermore, a finite element model is developed on the ANSYS 2021 R1 software platform with the employment of a Shell 63 element. Numerical outcomes are also in good agreement with the experimental data, affirming the validity and reliability of the findings. In addition, parameter analysis results indicate that the distortion angle remains approximately constant at a location approximately 1/10 of the span from the mid-span cross-section of the box girder, regardless of changes in the span-to-depth ratio. Increasing the web thickness yields a notable reduction in the distortion effects, and decreasing the wall thickness can effectively mitigate the distortion-induced transverse bending moment. Compared with normal-strength concrete box girders, UHPC box girders can reduce the distortion angle within the span range, which is beneficial for maintaining the overall stability of the box girders. The outcomes obtained from this study yield engineers an enhanced understanding of distortion effect on the UHPC girder performance. Full article
