The need to develop ecologically friendly sustainable building materials is made apparent by the worldwide construction industry's substantial contribution global greenhouse gas emissions. use of supplemental in concrete one potential solution lessen environmental footprint. Thus, purpose this work Machine Learning (ML) algorithms forecast and create an empirical formula for Compressive Strength (CS) with materials. Six distinct ML models—XGBoost, Linear Regression, Decision Tree, k-Nearest Neighbors, Bagging, Adaptive Boosting—were trained tested using a dataset that included 359 experimental data varying mix proportions. most significant factors used as input parameters are cement, aggregates, water, superplasticizer, silica fume, ambient curing, material. Several statistical measures, such Mean Absolute Error (MAE), coefficient determination (R2), Square (MSE), were evaluate models. XGBoost model outperformed other models R2 values 0.99 at training stage. To ascertain how affected outcome, feature importance analysis Shapely Additive exPlanations (SHAP) was conducted. It demonstrated curing age cement type significantly strength high SHAP values. By eliminating procedures, reducing demand labor resources, increasing time efficiency, offering insightful information enhancing manufacturing concrete, research advances low-cost production USA industry.

Machine learning for predicting compressive strength of sustainable cement paste incorporating copper mine tailings as supplementary cementitious materials

Case Studies in Construction Materials, Год журнала: 2024, Номер 21, С. e03373 - e03373

Опубликована: Июнь 7, 2024

Copper mining produces significant amounts of copper mine tailings (CMT), necessitating appropriate waste handling and disposal practices. By substituting a portion cement with CMT as supplementary cementitious materials (SCMs), we aim to address two environmental issues simultaneously: reducing in landfills decreasing embodied carbon by using less cement. The exploration recycling replacement requires evaluation its impact on material performance, such compressive strength. In this paper, machine learning that features data fusion large public our own small strength CMT-incorporated We developed critically evaluated three models: simple linear model, Gaussian process, random forest predict the pastes different mix designs (e.g., varying water-binder ratios) curing ages. Hyperparameters model were tuned Bayesian optimization. Following comprehensive models, find can accurately estimate paste across designs. Furthermore, results from SHapley Additive exPlanation (SHAP), Individual Conditional Expectation (ICE), Partial Dependence Plots (PDP) revealed cement, ground-granulated blast furnace slag, superplasticizers, ages positively influence This study contributes acceleration sustainable technology obtain best design desired

This study investigates the application of artificial intelligence (AI) to predict compressive strength self-compacting concrete (SCC) through ultrasonic measurements, thereby contributing sustainable construction practices. By leveraging advancements in computational techniques, specifically neural networks (ANNs), we developed highly accurate predictive models forecast SCC based on pulse velocity (UPV) measurements. Our findings demonstrate a clear correlation between higher UPV readings and improved quality, despite general trend decreased with increased air-entraining admixture (AEA) concentrations. The ANN show exceptional effectiveness predicting strength, coefficient (R2) 0.99 predicted actual values, providing robust tool for optimizing mix designs ensuring quality control. AI-driven approach enhances sustainability by improving material efficiency significantly reducing need traditional destructive testing methods, thus offering rapid, reliable, non-destructive alternative assessing properties.
