The Influence of Surveying Method on Mechanical-Electrical Properties of Smart Mortar
To a certain mortar, the identical measuring means can results in quite difference .Through determination intelligence concrete mortars mechanical –electrical with direct current ,alternating circuit,direct bridge and alternating electric bridge,the authors points out the outcomes stability from direct current and direct bridge get worse because they can´t dispel polarization existed in mortar itself. On the contrarory , both alternating circuit and alternating electric bridge can . At the same time, The authors discussed the influence on impedance (Z) of difference equivalent and frequency, and found that the using of series connection and high frequency sine wave can released impedance Z in this materials.
