Paper Title:
Experimental Study on Electrical Conductivity of Steel Fiber Concrete under Uniaxial Compression
  Abstract

Concrete is a key support material of underground chamber, its stress state is important parameter that can characterize the stability of underground chambers. The changing rule of the electrical conductivity of C50 steel fiber concrete in relation to the changes of the current, voltage and pressure was studied experimentally. And resistivity-stress regression equations of the concrete was fitted with much high correlation coefficient. Research results show that: (1) within the framework of elastic deformation, the electrical conductivity of concrete increases with the strengthening pressure (i.e., the concrete resistivity decreases with increasing pressure); (2) there exists the good correlation between the resistivity and pressure of the concrete; (3) given the certain pressure, the conductivity of the concrete is to some extent unaffected by voltage and current.
