The sustainable use of industrial byproducts in civil engineering is a global priority, especially reducing the environmental impact waste materials. Among these, coal ash from thermal power plants poses significant challenge due to its high production volume and potential for pollution. This study explores controlled low-strength material (CLSM), flowable fill made ash, cement, aggregates, water, admixtures, as solution large-scale utilization. CLSM suitable both structural geotechnical applications, balancing management with resource conservation. research focuses on two key properties: flowability unconfined compressive strength (UCS) at 28 days. Traditional testing methods are resource-intensive, empirical models often fail accurately predict UCS complex nonlinear relationships among variables. To address these limitations, four machine learning models-minimax probability regression (MPMR), multivariate adaptive splines (MARS), group method data handling (GMDH), functional networks (FN) were employed UCS. MARS model performed best, achieving R

Abstract A cement‐based material that meets the general goals of mechanical properties, workability, and durability as well ever‐increasing demands environmental sustainability is produced by varying type quantity individual constituents in high‐performance concrete (HPC) ultrahigh‐performance (UHPC). Expensive time‐consuming laboratory experiments can be used to estimate properties mixtures elements. As an alternative, these attributes approximated means predictive models created through application artificial intelligence (AI) methodologies. AI approaches are among most effective ways solve engineering problems due their capacity for pattern recognition knowledge processing.

Abstract Fiber‐reinforced polymer (FRP)‐confined double‐skin tubular columns (DSTCs) are an innovative type of hybrid that consist outer tube made FRP, inner circular steel tube, and a concrete core sandwiched between them. Available literature focuses on hollow DSTCs with limited research tubes filled concrete. Overall, have many applications, highlighting the importance studying effects filling strength composite system. To address this gap, finite element models (FEMs) both traditional machine learning (ML) techniques were used to develop accurate for predicting load‐bearing capacity confined ultimate strain under axial loads. A comprehensive database 60 experimental tests 45 FEMs simulations was analyzed, five parameters selected as input variables ML‐based models. New like gradient boosting (GB), random forest (RF), convolutional neural networks, long short‐term memory compared established algorithms multiple linear regression, support vector regression (SVR), empirical mode decomposition (EMD)‐SVR.
