FIELD: measuring technology.
SUBSTANCE: method for determining specific electric conductivity of concrete includes measuring full electric resistance relatively to previously saturated sample and following calculation of specific electric conductivity on basis of formula. Firstly, spherical sample is made, positioning spherical metallic insert in its center with metallic clamp. Clamp is isolated from concrete. Then sample is placed in metallic vessel, which is previously filled with current-conductive liquid. Measurement of full electric resistance is performed between metallic vessel and metallic clamp.
EFFECT: increased precision and speed of measurement of specific electric conductivity of concrete.
