摘要：

This study investigated the piezoelectric response of a smart concrete (MSF) containing fine steel slag aggregates (FSSAs) and steel fibers under high compression by measuring the alternative current impedance. The electrical resistivity of MSF notably decreased (15.65%) with the increase in the applied compressive stress from 20 to 100 MPa, whereas the electrical resistivities of smart concretes containing only FSSAs or steel fibers or both multiwalled carbon nanotubes and steel fibers reduced by 9.62, 12.37, and 9.30%, respectively. The MSF with a linear piezoelectric response under compression (until 60 MPa) was applied to a prestressing steel anchorage zone to monitor the loss of prestressing stress. (C) 2019 Elsevier Ltd.
