Evaluation of Coarse Aggregate Quality Grade of Recycled Concrete in China Based on Entropy Weight Extension Theory
摘要
Abstract
The comprehensive evaluation of coarse aggregate quality grade of recycled concrete is a complex decision problem involving multiple parameter indexes.A new model of recycled coarse aggregate quality grade based on entropy weight extension theory is proposed, and according to "Renewable coarse aggregate standards for concrete"(GB/T 25177-2010), the seven indexes such as apparent density, porosity and robustness are selected as the evaluation factors of the quality grade evaluation.Firstly,based on the theoretical knowledge of extension science,on the basis of introducing the classical domain,the section domain and the material element to be evaluated,the material element system of quality evaluation of coarse aggregate of recycled concrete is established by means of matter-element transformation, and the correlation coefficient of each index is calculated.Then, the entropy weight method is used to determine the weight coefficient of the matter-element index system, and the entropy weight matter element extension evaluation model is established to evaluate the coarse aggregate quality grade of recycled concrete.Finally, the experimental results of five batches of recycled coarse aggregate from a literature were used to evaluate the quality grade,the validity and reliability of the model were verified.关键词
