Relation Between Compressive and Tensile Strength of …

The tensile strength of concrete is more sensitive to inadequate curing than the compressive strength, possibly because the effect of non-uniform shrinkage of flexure test beams are very serious. Thus air-cured concrete has a lower ft/fc´ ratio than concrete cured in water and tested wet.

Properties of concrete - Wikipedia

The ultimate strength of concrete is influenced by the water-cementitious ratio (w/cm), the design constituents, and the mixing, placement and curing methods employed. All things being equal, concrete with a lower water-cement (cementitious) ratio makes a stronger concrete than that with a higher ratio.

Tension Vs. Compression of Concrete Hunker

Steel has great tensile strength; it bends without breaking. The combination produces the strength needed for bridge girders, roadways, building walls and other construction. An even stronger combination is prestressed concrete. The reinforcing steel is stretched or put under tension before concrete is poured around it.
