摘要:...55 were prepared to monitor electrical resistivity for a period of 24 h from casting using non-contact electrical resistivity measurement. A general equation \(\rho (t) = K_{\text{P}} \left( {1 - V_{\text{a}} } \right)^{ - m} \ln (Dt)\) was obtained from the electrical resistivity...

摘要:... Therefore, in actual structures, it is usually not correct to measure the resistivity of concrete by using the direct method because the electrodes’ area is smaller than the cross section of the concrete piece. In this experimental research the influence of the area and...

摘要:In a previously published work, performances of three practical earthing systems consists of 2, 3 and 4 rod-bed electrodes buried at the same site, thus the same soil resistivity were investigated. It was found that the degree of reduction of the earth resistance values is the hi...
