Elastic Modulus Prediction for Manufactured Sand Concrete Using Fuzzy Set and Neural Network

Abstract

The application of concrete with manufactured sand instead of natural sand is becoming increasingly prevalent. However, due to the inherent differences in the physical properties of manufactured and natural sand, it is not possible to apply the modulus of elasticity formula for natural sand concrete directly to manufactured sand concrete. Given that the combination of fuzzy rule modelling and neural network technology has been applied to data prediction, a prediction method based on fuzzy set and BP neural network model is constructed for the purpose of predicting the elastic modulus of manufactured sand concrete. The predicted value is then compared with the target value. The results demonstrate that the predictive model exhibits superior performance. The predictive model may serve as a point of reference for analogous studies.
