Prediction of concrete coefficient of thermal expansion and other properties using machine learning

Construction and Building Materials, 2019
The coefficient of thermal expansion (CTE) significantly influences the performance of concrete. However, CTE measurements are both time consuming and expensive; therefore, CTE is often predicted from empirical equations based on historical data and ...
