A causal evidential reasoning rule-based method for concrete compressive strength prediction
Concrete compressive strength is a key indicator for measuring structural performance and durability. Its accurate prediction is essential for engineering safety and construction quality. However, concrete strength is influenced by many material and environmental factors, making...
