  • Compressive strength - Wikipedia

In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled ...


  • Tension Vs. Compression of Concrete | Hunker

    Concrete has almost no tensile strength, the ability to withstand pressing or stretching. Put a board between two supports and press down on the center. It will bend. The top of the board is under compression, the bottom which bends is under tension. Concrete can resist the compression, but will break under the tension.

  • What is tensile strength of concrete - answers.com

    Tensile strength is one of the basic and important properties of the concrete. The concrete is not usually expected to resist the direct tension because of its low tensile strength and brittle nature.


  • Effect of Concrete Strength and Slab Thickness on Floor ...

    The specification for the floor of a maintenance building called for a 6-inch slab thickness and concrete with a design compressive strength of 3000 psi. The actual average cylinder strength for the floor concrete was 3630 psi. Four months after the floor was placed, 10 cores were drilled, measured, and tested in compression.


  • Properties of Concrete every civil engineer must know

    Apr 08, 2018· The tensile strength of concrete is an important property which affects the extent & width of cracks in the structure. A good concrete should have a tensile strength of 1/10 times that of compressive strength. As per IS 456: 2000 the tensile strength of concrete can be calculated from characteristic cube compressive strength. Tensile Strength ...

  • Compressive and Tensile Strength of Concrete: Relation ...

    Tensile strength of concrete is found more sensitive to the inade­quate curing than compressive strength. This may be due to the non -uniform shrinkage of flexural test beams. As flexural test beams are very sensitive to shrinkage cracks and are very serious for the test.


  • Tensile Test on Concrete - Building Research Institute (P ...

    Due to difficulty in applying uniaxial tension to a concrete specimen, the tensile strength of the concrete is determined by indirect test methods: (1) Split Cylinder Test (2) Flexure Test. It should be noted that both of these methods give the higher value of tensile strength than the uniaxial tensile strength.
