The Effect of Traffic Induced Vibrations at Early Concrete Ages on Concrete Tensile Strength

Abstract:

Article Preview

Four combinations of frequency and amplitude induced vibrations and six start vibrated ages which ensured that the concrete would be exposed to vibration in each of the following age ranges: before initial set, during the setting process, and after final set are designed in the test. The purpose of the test is to testify whether the induced vibrations would affect the attainable tensile strength of concrete at cure ages of 1, 3 and 28 days. The splitting tensile tests are performed and 76 splitting tensile strength results are acquired. There are 29 groups splitting tensile strength weaker than the control group. Of the 29 results, they are all less than 10% compared to control ones, and the ones those less than 7% account for 76% of the weaken results. The test results have shown that, the induced vibrations designed in the test have a slight negative effect on the attainable the splitting tensile strength of concrete.
