The use of supplementary cementitious materials can reduce the quantity of cement required, thus lowering CO₂ emissions.

The study utilizes 54 experimental data points from geopolymer concrete mixtures containing sugarcane bagasse ash, collected through experimental work, to develop and assess the prediction models. The models are evaluated using various metrics, including the coefficient of determination (R²), root means squared error (RMSE), scatter plot analysis, and mean absolute error (MAE).
