Compressive and Tensile Strength of ConcreteRelation
The ratio of tensile strength to compressive strength depends upon the strength of concrete. Thus higher the compressive strength, higher the tensile strength, but the rate of increase of tensile strength is of decreasing order. The tensile strength of concrete is more sensitive to improper curing than the compressive strength.

What are the differences between flexural and tensile
Tensile strength is the maximum amount of engineering tensile stress a material can withstand. Engineering stress is (applied force)/(initial cross sectional area). Flexural strength is the maximum amount of bending it can withstand.
Why Does Concrete Have Great Compressive Strength, But
Tensile strength of concrete. The tensile strength of a material is simply the measurement of the force required to pull something to the point that it breaks. In other words, you could say that the tensile strength of a material is the maximum tension it can withstand without breaking.
