Prediction of Compressive Strength of CSGR Based on Optimized Machine Learning with Sparrow Search Algorithm

Abstract Cemented sand, gravel, and rock (CSGR) is an emerging dam material, and accurately predicting its compressive strength is essential for reliable mix-proportion design. Using 342 experimentally measured samples, this study develops an SSA-optimized machine-learning framew...
