“…Basalt fibre possesses the capability to shift the failure mode of Basalt Fibre-Reinforced Polymer Composites (BFRPC) from tensile failure to tensile shear failure. Additionally, it effectively increases the stress level during cracking, consequently minimizing damage in BFRPC [141]. This observation implies that UHPBFC demonstrates enhanced thermal resistance when subjected to elevated temperatures [142].…”

“…Currently, the research on the effects of water on mortar primarily focuses on the mixing water, such as the water content of mortar, the water-to-cement ratio, sand gradation, pH value of the water, and the effects of magnetized and electrolyzed water on the workability and strength of the mortar [2][3][4][5][6][7][8][9][10][11][12][13][14]. On the other hand, studies on the effects of environmental water on the mechanical properties of rocks are well-documented [15][16][17][18][19][20][21], which have pointed out that the action of water can reduce the strength and toughness of rocks.…”

Urban underground engineering is generally buried at a shallow depth and suffers long-term environmental water effects such as rainfall, rivers, underground pipeline leakage, and groundwater. The mechanical properties of the structures are affected by constant deterioration, which seriously hinders the safe, healthy, and sustainable development of the city. On the basis of on-site investigation of civil defense engineering, this article simulates the water environment conditions of mortar in underground engineering in the laboratory and conducts manual sample preparation in the laboratory. Then, water, H2CO3, NaCl, and Na2CO3 solution or wet–dry cycles are used to corrode the sample, respectively. A uniaxial compression test, Brazilian splitting test, analyses of the acoustic emission signals and electromagnetic signals, and magnetic imaging testing are performed, respectively. The results show that an increase in the action time of environmental water leads to a gradual increase in the uniaxial compressive strength, tensile strength, and elastic modulus of cement mortar, but it will decrease over a long period of time. Different environmental water components can also lead to a different performance of soaked mortar. The uniaxial compressive strength R, tensile strength σt, and elastic modulus E of mortar samples exhibit values in different solutions in the order of H2CO3 solution < NaCl solution < Na2CO3 solution < water. A moderate solution soak time can enhance the mechanical properties of the mortar, but this effect decreases at long time scales. The effect of wet–dry cycles on the mechanical properties and degradation process of mortar is significant. With the increase in wet–dry cycles, the porosity of mortar continuously increases. The cumulative ringing count, energy, amplitude, and impact number of acoustic emission signals always increase when the samples are loaded to failure. The uniaxial compressive strength, tensile strength, and elastic modulus first increase and then decrease. The experimental results lay the foundation for further investigating the performance changes in mortar under complex water environments in underground engineering.

“…It was found that increasing the thickness of the baseplate can increase the flexural capacity of the formwork, and increasing the thickness of the sidewalls can increase the shear capacity, and a method for calculating the shear capacity was proposed. In summary, it was found that the failure process of stacked structures differed less from that of cast-in-place structures provided that the interfaces of the composite structures were well bonded [24]. However, most of the theoretical analyses of the tests mentioned above were for the frame girder form, with fewer studies involving the capping beams.…”

Basalt Fiber Reactive Powder Concrete (BFRPC) semi-prefabricated composite capping beam structures can effectively improve the shortcomings of ordinary concrete capping beams' construction difficulties and insufficient bearing capacity. In this study, with the objective of analyzing the shear damage and damage characteristics of a prefabricated BFRPC capping beam formwork, structural damage tests under different levels of loading were carried out to obtain the mechanical parameters of key nodes. Acoustic emission (AE) and Digital Image Correlation (DIC) techniques were used to acoustically and visually characterize the formwork damage. The research results showed that the damage stage of the capping beam formwork was divided, and an early damage warning method was proposed based on the acoustic parameters. Using the DIC technique to identify the crack width evolution pattern during the shear process, it was found that the cracks expanded steadily as the load increased. Combining the experimental and simulation results as well as the Subdivision Superposition Theory, a half-open stirrup strength discount factor β was introduced and suggested to take a value of 0.79. The formula for calculating the shear capacity of BFRPC capping beam formwork is proposed to provide a theoretical basis for its application in prefabricated assembled structures.
