Machine Learning Modelling for Compressive Strength Prediction of Superplasticizer-Based Concrete
Infrastructures, 2023 Superplasticizers (SPs), also known as naturally high-water reducers, are substances used to create high-strength concrete. Due to the system’s complexity, predicting concrete’s compressive strength can be difficult. In this study, a prediction model for
