Investigation on Interfacial Behavior of Modified Basalt Textile Reinforced Concrete Using Acoustic Emission Technique
The tetrahedral structure of the basalt fabric is damaged when it is corroded by hydroxide ions, which greatly limits its application in the field of construction engineering as a result of the concrete matrix present in a strongly alkaline environment (pH >12.5). In this investigation, the alkal...

| description | The tetrahedral structure of the basalt fabric is damaged when it is corroded by hydroxide ions, which greatly limits its application in the field of construction engineering as a result of the concrete matrix present in a strongly alkaline environment (pH >12.5). In this investigation, the alkali-resistant basalt fabric was successfully assembled by structuring mussel-inspired polydopamine (PDA) and zirconia (ZrO2) coatings on fabric surfaces. SEM, SWCA, XRD, FI-IR, RS, and XPS were used to analyze them. The mechanical properties of the different basalt fiber bundles accelerated aging in sodium hydroxide solution were tested. The interfacial behavior between basalt fiber bundles before and after modification and concrete matrix was studied by the acoustic emission (AE) technique. The results illustrated that dense PDA and ZrO2 coatings were dropped onto the surface of the basalt fabric. After being corroded by alkali solution, the final strength retention ratio of modified fabrics was superior to the original basalt fabric. Load–displacement curves of interfacial behavior could be well correlated with AE data in different loading stages of damage initiation, evolution and propagation. A five-stage linear local bond-slip model was proposed to describe the interfacial process between a basalt fiber bundle and concrete. |
