Contact网页2 天前 The tensile strength of concrete describes the concretes ability to resist forces trying to pull the concrete apart. These forces usually derive from bending actions which cause tensile stresses in the bottom of the concrete. The tensile strength of concrete is particularly low, especially when compared to its compressive strength which is high.

Contact网页2018-12-15 To test tensile strength, there are several different tests that can be performed. The first is a flexure test, which tests how much motion the concrete can take before it breaks. The second places direct tension

Contact网页Tensile strength can be tested three ways: direct tension, splitting tension, and flexural tests. Results of these tests differ, and results of tests made on cores taken in the field differ from results made on laboratory specimens. Some 12,000 individual test results were examined to find reason for these discrepancies.
