Divergent Hydration Kinetics: Type-Aware Artificial Intelligence Framework for Compressive Strength Prediction and Sustainability Evaluation in Concrete Composites

Abstract Artificial Intelligence (AI) offers significant utility for compressive strength prediction for concrete. However, existing data-driven approaches assume homogeneous material behaviours without accounting for the compositional differences in conventional and sustainable concrete. This study examines the feasibility of developing ‘material-aware’ machine learning models that are capable of predicting compressive strength, without overlooking how intrinsic properties of sustainable or conventional concrete govern microstructural stability, and in turn, the compressive strength. Concrete datasets were preprocessed to identify parameters with statistically relevant correlation with compressive strength. Feature Engineering was employed to introduce a novel attribute ‘type’ for each concrete instance in the datasets, and the attributes corresponding to concrete sustainability were segregated to be modelled for sustainability evaluations. Further analysis of the datasets revealed a pronounced anomalous behaviour between age and compressive strength. While age demonstrated a positive correlation with compressive strength in conventional concrete, a contrasting negative correlation was observed between age and compressive strength in sustainable concrete. This disparity revealed that both concrete types had divergent kinetic pathways during the hydration process; these differing behaviours were further explained by the presence of Supplementary Cementitious Materials (SCMs) and their distinct potential for Calcium Silicate Hydrate (C-S-H) gel generation. Under these conditions, Linear Regression (LR) and Random Forest (RF) models were trained and evaluated using R^2,MAE and MSE. The results indicated that the majority of compressive strength correlations with concrete properties were non-linear, justifying Random Forest’s more robust and precise predictive capability. The RF model significantly outperformed the linear baseline model, achieving a near-perfect R^2 of 0.993, compared to 0.831 for LR, confirming the non-linear nature of the predictor-target interactions in concrete. The research further translated the predictive results into user-friendly Graphical User Interfaces (GUIs) that allow compressive strength estimation and sustainability assessment. Collectively, the findings of this research highlight the significance of incorporating material classification into AI-driven modelling of concrete properties and demonstrate how domain-informed machine learning can enhance both predictive accuracy and real-world usability. The study contributes a practical and scalable framework for integrating intelligent modelling into sustainable construction analysis and decision-making workflows, providing a meaningful resource for engineers and field experts.
