Abstract

The invention discloses a device and a method for measuring corrosion rate of concrete iron along length direction, and belongs to the field of concrete construction. The device comprises a table, a fixing device, a measuring device and a data acquisition device. The fixing device comprises a fixing frame and a fixture; and the fixing frame is provided with scale. The measuring device comprises a container, water and an automatic weighing device, and the water is positioned inside the container. The data acquisition device comprises a computer. One end of the fixture is arranged on the frame and capable of moving up and down, and the other end of the fixture is fixed at the upper end of the concrete iron; and the lower end of the concrete iron is placed in the water. The fixing frame is arranged on the automatic weighing device, which is connected to the computer through wires. The container and the automatic weighing device are arranged on the table. The measuring device has characteristics of simple assembly, convenient operation, few devices needed for testing and repeat usage, and can accurately measure the corrosion rate of the concrete iron along length direction.

Description

technical field [0001] The invention relates to a device and a measuring method for measuring the corrosion rate of steel bars along the length direction, belonging to the field of concrete construction. Background technique [0002] In the field of civil engineering, steel bars and concrete are currently the most widely used building materials in the world. A large number of building structures are made of reinforced concrete. However, due to concrete carbonation and chloride corrosion, steel bars are corroded and the structure is reduced. Therefore, the research on the corrosion of steel bars is a durability problem that needs to be solved urgently in engineering. [0003] At present, most of the methods for measuring the corrosion rate of steel bars adopt the method stipulated in "Test Methods for Long-term Performance and Durability of Ordinary Concrete" (GBJ82-85): Take out the steel bars in the test piece, scrape off the concrete attached to the steel bars, and use 12%...
