Marine experimental method of steel reinforcement cage built-in concrete

Abstract

The invention relates to the field of durability of reinforced concrete and aims to provide a marine experimental method of steel reinforcement cage built-in concrete. According to the method, a blocky concrete test piece is placed at a testing position of a sea tidal zone, and the concrete test piece is regularly detected; a steel reinforcement cage with a three-dimensional cage structure is built in the concrete test piece; the selected testing position of the sea tidal zone should have sea tidal action, that is to say, it is ensured that the time for the concrete test piece to be contacted with seawater within a day should be 8-16h. By selecting a sea tidal environment, a real work environment is provided for the test piece. By selecting the concrete test piece, safe service of the test piece in the testing process is guaranteed. By the built-in steel reinforcement cage, an internal material composition environment of reinforced concrete is more truly shown.

Description

technical field [0001] The invention relates to a reinforced concrete marine test method, which belongs to the field of reinforced concrete durability and also belongs to the field of marine environment tests. Background technique [0002] With the rapid development of my country's marine economy, the anti-corrosion of marine engineering facilities has become an important issue that needs to be solved urgently in the development. In the marine environment, performance degradation and cracking of reinforced concrete caused by marine corrosion factors such as chloride ion erosion have brought huge economic losses to marine countries around the world. According to the statistical rule that corrosion loss accounts for about 3% of GDP, my country's corrosion loss in 2014 reached 1.9 trillion yuan, of which marine corrosion accounted for a very large proportion. Therefore, the research on the durability of reinforced concrete materials in the marine environment is attracting grea...

Problems solved by technology

[0006] In addition, the current durability test methods for concrete are mostly for the concrete material itself, and less built-in metal materials

In actual marine engineering or sea-related buildings, concrete structures contain a large number of steel bars of various specifications, so it is difficult to fully express the durability of reinforced concrete structures only by the durability of concrete materials
