The construction industry is making efforts to reduce the environmental impact of cement production in concrete by incorporating alternative and supplementary cementitious materials, as well lowering carbon emissions. One such material that has gained popularity this context rice husk ash (RHA) due its pozzolanic reactions. This study aims forecast compressive strength (CS) RHA-based (RBC) examining effects several factors cement, RHA content, curing age, water usage, aggregate amount, superplasticizer content. To accomplish this, collected analyzed data from literature, resulting a dataset 1404 observations. Several machine learning (ML) models, light gradient boosting (LGB), extreme (XGB), random forest (RF), hybrid (HML) approaches like XGB-LGB XGB-RF were employed thoroughly analyze these parameters assess their on strength. was split into training testing groups, statistical analyses performed determine relationships between input CS. Moreover, performance all models evaluated using various evaluation criteria, including mean absolute percentage error (MAPE), coefficient efficiency (CE), root square (RMSE), determination (R2). model found have higher precision (R2 = 0.95, RMSE 5.255 MPa) compared other models. SHAP (SHapley Additive exPlanations) analysis revealed RHA, had positive effect Overall, study's findings suggest with identified can be used accurately predict CS RBC. application technologies sector facilitate rapid low-cost identification qualities parameters.

The incorporation of waste foundry sand (WFS) into concrete has been recognized as a sustainable approach to improve the strength properties (WFSC). However, machine learning (ML) techniques are still necessary forecast characteristics WFSC and evaluate dominant input features for suitable mix design. For this purpose, present work selected five ML-based based on gene expression programming (GEP), deep neural network (DNN), optimizable Gaussian process regressor (OGPR) predict mechanical WFSC. To build up predictive models, database containing 397 values compressive (CS) 169 flexural (FS) is collected from published literature. models' performance was evaluated via various statistical metrics additionally, external validation criteria were employed validate developed models. Furthermore, Shapley additive explanation (SHAP) carried out interpret model's prediction. DNN2 model exhibited superior performance, with R-values 0.996 (training), 0.999 (testing), 0.997 (validation) estimation. In contrast, GEP2 showed poor accuracy in estimating CS compared other 0.851, 0.901, 0.844 training, testing, sets, respectively. Similarly, estimation, provided indicating its robust performance. SHAP analysis revealed that age, water-cement ratio, coarse aggregate-to-cement ratio have prime influence determining strength, comparison models accurately estimated output high lower error might be utilized practical fields reduce labor cost by optimizing combinations. Finally, future studies, it recommended utilize ensemble hybrid algorithms, well post-hoc explanatory techniques, accurately.
