Concrete Flexural Modulus
Concrete Flexural Modulus
(OP)
I am trying to find the Flex Modulus for 9,000 psi concrete. It seems that is not tested for on a regular basis. I have the Flex. strength as 1,600 psi. Any help would be appreciated. Thanks

RE: Concrete Flexural Modulus
You're right...not much has been done for flexure comparisons with high strength concrete.
I would probably not bank on 1600 psi. Probably more in the 800-1000 psi range, assuming #57 stone or similar coarse aggregate.

In addition to the aggregate size, the angularity of the aggregate has a significant impact on the flexural tensile strength.
