“…In order to establish the relationship between concrete strength and pore structure, the grey correlation analysis method has been applied the main factors that affect the system [ 20 , 21 , 22 ]. However, this method has the disadvantages of partial correlation tendency and loss of individual information, which cause significant deviation of the grey correlation degree and affects the analysis results [ 23 , 24 ]. Mokhtar et al [ 25 ], Jin [ 26 ], Chen [ 27 ], Xie et al [ 28 ], used the Grey Relational Entropy (GRE) analysis method to study the influencing factors and laws of concrete strength, which was proved to be a simple and effective method.…”

The Grey Relation Entropy (GRE) theory is used to analyze the sensitive pore size that affects the compressive strength of concrete. The relationship between the strength and pore structure is revised based on the sensitivity coefficient. The revised model is used to calculate the compressive strength of concrete. In order to verify the validity of the proposed model, the calculated results are compared with experimental ones, showing satisfactory agreement with a larger correlation than existing methods.
