Abstract

The invention provides a loading device for testing concrete chloride ion permeability by coulometry. A steel bottom plate is provided with two screw holes; two parallel screws are inserted into the screw holes; an underdraught steel plate, an overdraught steel plate and a top plate which are parallel to the steel bottom plate are sleeved on the screws sequentially; a jack is arranged between the top plate and the overdraught steel plate; a dynamometer is arranged between the overdraught steel plate and the underdraught steel plate; the steel bottom plate is provided with a convex steel support upwards; the underdraught steel plate is provided with a convex steel pressing head downwards; a overdraught steel plate positioning bolt cap is sleeved on one screw on the upper part of the overdraught steel plate; and a top plate positioning bolt cap is sleeved on the other screw on the upper part of the top plate. The invention also provides a method for testing the concrete chloride ion permeability by the coulometry by utilizing the loading device. The loading device solves problems that the conventional concrete chloride ion permeability testing device cannot apply bending loads on tested pieces, cannot simulate the actual load-up condition of in-service concrete members, and cannot measure the concrete chloride ion penetrability under the condition of the bending loads.

Description

technical field

[0001] The invention relates to a loading device for testing the chloride ion permeability of concrete by the electrical method, in particular to a loading device for performing the chloride ion permeability electrical method test on the concrete under a bending load condition, and the invention also relates to a test using the loading device method. Background technique

[0002] Chloride ion permeability is not only an important index to characterize the permeability of concrete, but also an indicator for the corrosion resistance of steel bars in reinforced concrete in environments with high chloride ion content (such as seaport terminals, underground engineering, hydraulic structures and reinforced concrete poles in coastal areas). important sign. The current methods for measuring the chloride ion permeability of concrete mainly include the electric quantity method and the rapid chloride ion migration method, but the test pieces in the two methods do not i...
