Abstract
Predicting concrete compressive strength using machine learning techniques has attracted the focus of many studies in recent years. Typically, given concrete mix ingredients, a machine learning model is trained on experimental data to predict properties of hardened concrete, such as compressive strength at 28 days. This study used computer-generated mix design data that contained mixed ingredients along with the corresponding theoretical strength of each mix to train a neural network and then test them on real-world experimental data. The developed model was able to predict the compressive strength of concrete specimens at 28 days with an R-value of 0.80. Furthermore, increasing the synthetic dataset increased the performance of the model to a point beyond which it started to decrease. The proposed sustainability-promoting method emphasizes the effectiveness of using synthetic data to train machine learning models that yield insightful predictions with acceptable accuracy.
