How Is The Tensile Strength Of Concrete Measured?

Mar 29, 2021 · Tensile strength is measured in units of force per cross-sectional area (N/SQ.mm or Mpa). Testing for tensile strength can be difficult due to the material’s tendency to break or crack, and this is why tensile strength is usually measured via indirect methods rather than a direct method known as a uniaxial tensile test.
