Optimizing Concrete Mix Designs With Synthetic Data Generation and Machine Learning Prediction Models

open access: yesApplied Computational Intelligence and Soft Computing, Volume 2025, Issue 1, 2025.
The focus of this paper is on the use of machine learning for the prediction of the strength outcomes of basalt fiber‐reinforced concrete (BFRC), based on its mechanical properties. These target properties are compressive, flexural, and tensile strengths, estimated with knowledge of 10 variables, including cement and aggregate content, among other ...
