testing of concrete for compressive strength and qua
Relation Between Compressive and Tensile Strength of Concrete
The tensile strength of concrete is more sensitive to inadequate curing than the compressive strength, possibly because the effect of nonuniform shrinkage of flexure test beams are very serious. Thus aircured concrete has a lower ft/fc´ ratio than concrete cured in water and tested wet.

Concrete Strength Testers | Qualitest
The range of instruments is typically considered to be two parts. The first are nondestructive field tests of compressive strength. The second are tensile field tester systems to either determine the tensile strength of an overlay or bond material, or tensile strength of anchors embedded in the concrete.
