increasing cement tensile strength

  • FIBER ADDITION AND ITS EFFECT ON CONCRETE STRENGTH

    The fibers are able to prevent surface cracking through bridging action leading to an increased impact resistance of the concrete. The addition of steel fibers to concrete considerably improves its properties of concrete in the hardened stage such as flexural strength, impact strength, tensile strength, ductility and flexural toughness.

  • Tensile strength

    There are three typical definitions of tensile strength: Yield strength - The stress a material can withstand without permanent deformation. This is not a sharply defined point. Yield strength is the stress which will cause a permanent deformation of 0.2% of the original dimension. Ultimate strength - The maximum stress a material can withstand.

First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may

  • Tensile strength of unreinforced concrete?

    All Answers ( 18) The range for the tensile strength of concrete is about 2.2 - 4.2 MPa. For low strength class concrete, as mentioned by Saber, the tensile strength of unreinforced concrete equals 1/10 the compressive strength, and for higher class, it is about 1/15. A good reference where this is mentioned is the book by S U Pillai Reinforced
