In this paper, a long-term study on the interface performance of GFRP-RC beams was conducted over an 8-year period to investigate the long-term degradation characteristics of the interface materials and the long-term Effective Anchorage Length (EAL) of GFRP bars. Firstly, a comprehensive analysis from a review perspective was conducted on the long-term degradation mechanisms of concrete and GFRP bars that considers the chemical behavior between microscopic molecules, the two-dimensional (2D) structure observed through micro electron microscopy, and the three-dimensional (3D) structure revealed by micro-X-ray imaging. Secondly, a new EAL calculation model is derived, and the long-term variation parameters of EAL under different conditions are determined. It was observed that the influence of alkaline corrosion and sustained loading is relatively small compared to the influence of initial structural defects on EAL. Finally, a comparison with four international standards revealed that the anchorage length design provided by JSCE-97 and ACI 440–1R-15 is overly conservative for GFRP bars, with values approximately 2–3 times the test results. On the other hand, CSA-S806–12 and CSA S6–19 standards are relatively close to the test values. Considering both design rationality and long-term corrosion resistance, it is concluded that the CSA-S806–12 specification is more reasonable.</p></div>","PeriodicalId":9641,"journal":{"name":"Case Studies in Construction Materials","volume":"21 ","pages":"Article e03399"},"PeriodicalIF":6.2,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214509524005503/pdfft?md5=cbf68785f8189b318073cfe6f8ad4b3a&pid=1-s2.0-S2214509524005503-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141328668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The exploration of CMT recycling as a cement replacement requires evaluation of its impact on material performance, such as compressive strength. In this paper, we address this by machine learning that features data fusion of large public data with our own small data on compressive strength of CMT-incorporated cement. We developed and critically evaluated three machine learning models: a simple linear model, Gaussian process, and random forest that predict the compressive strength of CMT-incorporated cement pastes with different mix designs (e.g., varying amounts of CMT and water-binder ratios) and curing ages. Hyperparameters in the random forest model were tuned using Bayesian optimization. Following a comprehensive evaluation of the models, we find that the random forest model can accurately estimate the compressive strength of cement paste across the mix designs. Furthermore, results from SHapley Additive exPlanation (SHAP), Individual Conditional Expectation (ICE), and Partial Dependence Plots (PDP) revealed that cement, ground-granulated blast furnace slag, superplasticizers, and curing ages positively influence compressive strength.

The self-healing ability of FA/S-EGC was evaluated by crack characteristics, tensile properties and natural frequency-based damage factor. In addition, micro-characterisation techniques including SEM-EDS, XRD and FT-IR analyses were used to reveal the self-healing mechanism of FA/S-EGC. The results showed that FA/S-EGC retained strain hardening and multi-cracking behaviour after healing in an external alkaline environment. The healing products of FA/S-EGC in air, water and alkaline environments consisted mainly of the C(N)-A-S-H gel and calcium carbonate (CaCO₃), and the phase of the healing products did not change despite the different environments. The self-healing ability of FA/S-EGC in saturated Ca(OH)₂ and 7 % NaOH solutions was significantly improved compared to air and water. This is because the low concentration of the alkaline solution promotes the geopolymerisation of unreacted oxides in the matrix, and the Ca(OH)₂ solution also promotes the deposition of CaCO₃ at the cracks. However, when the NaOH concentration was increased from 7 % to 21 %, FA/S-EGC still showed significant self-healing behaviour in the first seven days, but new damage was produced in the matrix as the healing age increased. This is because the high concentration of NaOH solution leads to depolymerisation of C(N)-A-S-H gels.
