The Properties Studing Experimentally And The Service Life Predicting Of The Reinforcing Concrete Eroded By Boric Acid

The paper studied the changing process of the reinforcement concrete in a construction eroded by boron on the base of experimental, got the changing regular of the properties of the steel bar , the concrete and the adhesive strength between steel bar and concrete, and then the paper researched the reason for the properties to act such through microanalysis. Taking the test results as the criterion, this approach yields the deterioration degree and deterioration rate of the reinforcing concrete. Based on the assumption that deterioration varies with time, the residual service life is yielded. The paper presented the mechanism of the corrosion of boron on concrete, and summerized the kinds of influential factors on the erosion of boron on concrete, and the paper gave the suggests to the researchers who continue to apply the study according to the tests in this paper.
