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.

采用灰色关联熵（GRE）理论分析影响混凝土抗压强度的敏感孔径。基于灵敏度系数修正强度与孔结构之间的关系。利用修正后的模型计算混凝土的抗压强度。为验证所提模型的有效性，将计算结果与试验结果进行比较，结果表明与现有方法相比，该模型具有更高的相关性，吻合度良好。
