Abstract.Recycled aggregate concrete is an important approach for realizing the resource utilization of construction waste and alleviating the shortage of natural aggregates [1,2,4]. However, the engineering application of recycled coarse aggregate is severely limited by adhered old mortar, high porosity, and high water absorption [3-6]. In this study, microbially induced calcium carbonate precipitation (MICP) using Bacillus pasteurii was adopted to modify recycled coarse aggregate [7,13]. The optimal mineralization process was determined through single-factor tests, and the mechanical properties of … Read more →

Abstract.Using survey data from 386 grape growers in Yingkou City, this article examines whether e-commerce participation affects three distinct domains of growers’ behavioural upgrading: standardized production, diversified marketing, and green technology adoption. Unlike studies that treat behavioural change as a single aggregate outcome, this paper compares the relative sensitivity of each domain and discusses why different behavioural responses emerge under the same digital market condition. A regression framework based on the dissertation dataset shows that e-commerce participation exerts … Read more →
