QUALITY CONTROL OF THE UNIT OF CONCRETE ANCHORS USING THE ELECTROMETRIC METHOD
The results of modelling and mine research of the proposed potentiometric method of non-destructive quality control of the unit of concrete anchors are given. The essence of the method is to test the filling of the cavity hole with cement-sand using instruments to determine the electrical resistance and the two electrodes fixed in mass in the vicinity of the test anchor (three electrodes method). Mine tests showed a reliable relationship between the degree of filling of the reinforced concrete anchor with cement-sand mixture and transient electrical resistance.
