Description
Technical Field

Background
According to the standard of the test method for the long-term performance and the durability of common concrete (GB/T50082-2009), the concrete anti-chloride ion permeation test can be measured by adopting a rapid chloride ion migration coefficient method (or RCM method) or an electric flux method. The rapid chloride ion migration coefficient method (or RCM method) is used for determining the migration coefficient of the unsteady migration of chloride ions in concrete to determine the chloride ion permeation resistance of the concrete, and a cylindrical test piece with the diameter of 100+/-1 mm and the height of 50+/-2 mm is used as the test piece.

Splitting a test piece into two semi-cylinders along the axial direction on a pressure testing machine, and immediately spraying AgNO with the concentration of 0.1mol/L on the section of the split test piece 3 A solution color indicator. After the indicator was sprayed for about 15 minutes, the test piece was divided into 10 equal parts along its diametric section and a penetration profile was drawn using a water-resistant pen. Then, according to the observed obvious color change, the distance between the color development boundary and the bottom surface of the test piece is measured to be accurate to 0.1mm.
When a certain measuring point is blocked by the aggregate, the position of the measuring point can be moved to a position which is not blocked by the aggregate recently for measurement, and when the data of the certain measuring point cannot be obtained, the measuring point can be ignored as long as the total number of the measuring points is more than 5. When a certain measuring point has a significant defect, the measuring point is far larger than the average value of each measuring point, the measuring point data can be ignored, but the situation is noted in test records and reports.
At present, the concrete anti-chloride ion penetration test is used for measuring AgNO 3 When the penetration height of the solution color indicator is measured, the equal part and the height of the solution color indicator are measured by adopting a manual ruler, so that the time required is long, the working efficiency is low, the equal part and the height are not accurately measured, and the accuracy of the test result is further affected.
