tension strength for concrete

[robyengIT]

as far as You know, there is any literature about relation between tensile (not compressive) strength of concrete directly found in lab (with proper specimen) and the tensile strength indirectly found in lab with the cylinder specimen (brazilian test) ? Usually the standard provides a formula stating the tensile strength from the failure load of the brazilian test
Thanks

To my knowledge, there is no credible direct tension test for concrete. This is because there are many variables that affect concrete tensile tests. For instance, even a slight variation in distribution of the coarse aggregate in the concrete will change its tensile properties but not affect its compression properties.

The two common tests are splitting tensile and flexural tests. It is easy to do a correlation between splitting tensile and flexural as you can use the same specimen for both tests.

Here is a link to some additional information.....
