Question

Compressive strength and tensile strength relation

Answer 1

Answer:

The tensile strength of concrete is about the tenth of compressive strength.

The mean characteristics tensile strength fctm is related to mean cylinder compressive strength fcm as follow.

The 5% and 95% fractals of the characteristics tensile strength of concrete are,

respectively fctk,0.05=0.7fctm and fctk, 0.95=1.3fctm
