Concrete requires proper compaction to perform effectively. The compaction process requires skilled workers, extra time, and vibrators to minimize voids in the concrete and achieve the necessary strength and durability. Using self-compacting concrete (SCC) instead of normal concrete results in higher compressive strength (CS) and durability. Self-compacting concrete significantly benefits the construction process, including cost and time reduction, minimized labor, and improved overall performance. However, evaluating the compressive strength is crucial to ensure the SSC’s durability. Based on a sensitivity analysis chart in this study, some factors significantly influence the CS, such as age, coarse aggregate, and fly ash. This study investigates the effect of those factors on the CS of SCC by applying several modeling techniques for 123 different mixtures. The predictive modeling techniques used to predict the CS of SCC include Linear Regression, Non-Linear Regression, Multi-Linear Regression, Logarithmic, Pure Quadratic, Artificial Neural Network, and the M5P-tree. The independent variables in the obtained dataset are Cement with its value ranging between 141.5–530 kg/m<sup>3</sup>, Limestone 0–200 kg/m<sup>3</sup>, Fly Ash 0–275 kg/m<sup>3</sup>, Fine Aggregate 464.4–1014 kg/m<sup>3</sup>, Coarse Aggregate 480–957 kg/m<sup>3</sup>, Water 49.53–252 kg/m<sup>3</sup>, Super Plasticize 0.30–4.70 %, Fiber 0–80 kg/m<sup>3</sup>, and Age 1–56 days. The value of CS, which is a dependent variable in this study, is between 19.8 and 75.2 MPa. Among the models that have been evaluated, the Artificial Neural Network (ANN) model demonstrated the highest accuracy in predicting compressive strength, with superior results across all evaluation criteria. Also, the Multi-Linear Regression model (MLR) showed a high performance. The evaluation of residual error confirmed that the ANN model provided the smallest error compared to the other models. This study's findings highlight the models that accurately predicted the CS of SCC, along with the factors that had the most tremendous impact on the CS of SCC. </p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"26 8","pages":"3485 - 3506"},"PeriodicalIF":0.0,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These concrete mixture designs, involving complex, non-linear, multi-objective nature, often face optimization techniques of existing methods. Such traditional metaheuristics, though very useful, are not adaptable, slow in convergence, and not efficient in exploring large solution spaces under stringent performance constraints. This work presents a hybrid AI-quantum inspired multi-objective optimization framework for self-healing concrete design to deal with those challenges. The model integrates four developed computational techniques: (1) Quantum Inspired Differential Evolution with Adaptive Learning Mechanism (QIDE-ALM), improving exploration–exploitation balance using quantum bit-flipping and adaptive feedback; (2) Quantum-Accelerated Multi-Objective Particle Swarm Optimization (Q-MOPSO) that uses quantum tunneling to escape local optima and to speed up convergence; (3) Quantum-Driven Surrogate Modeling which uses quantum support vector machine and quantum neural network to reduce the computational burden on fast performance outcome prediction; and (4) Quantum Inspired Neural Networks for Multi-Objective Optimization (QINN-MO), dynamically learning complex relationships among mixture components by quantum Inspired weight modulation and architecture adaptations. Iterative implementation of this integrated model combines global searching with quick convergence and assessment, in conjunction with intelligent learning, generating Pareto-optimal concrete designs. The initial results show a tremendous improvement in performances: compressive strength of 50–55 MPa, healing efficiency in the range of 90–95%, and lifecycle cost reduction of up to 20%. This framework is expected to prove potent, scalable, and computationally efficient in advancing concrete technology, thus entirely revolutionizing practices in civil infrastructure through intelligent process engineering of quantum-enhanced materials. </p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"26 8","pages":"3471 - 3483"},"PeriodicalIF":0.0,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Free vibration analysis results demonstrate the exceptional efficiency and accuracy of the new element. The results obtained with the present element excel those obtained with standard ABAQUS elements and other non-conforming elements found in the literature. This superiority is noticeable in free vibration scenarios, demonstrating the effectiveness of the proposed finite element for accurate and reliable simulation of the vibrational behavior of thin plates.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"26 8","pages":"3341 - 3352"},"PeriodicalIF":0.0,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
