Pulkit Dilip Velani

One of the popular thumb rule is inputting tensile strength as 10% of compressive strength.

Prabhakar Gundlapalli

I agree with Mr. Pulkit's answer. 10% of Fck is a good and reasonable estimate. As the strength goes high, tensile stress limit comes down, and concrete becomes brittle. One should keep this in mind.
