It should be noted that both of these methods give the higher value of tensile strength than the uniaxial tensile strength. SplitCylinder Test. It is the standard test, to determine the tensile strength of concrete in an indirect way. This test could be performed in accordance with IS : 58161970.
Oct 28, 2013 · Specified concrete compressive strength is the minimum compressive strength at which the concrete should fail in standard tests of 28dayold concrete cylinders. A typical concrete compressive strength specifiion requires 4,000 to 5,000 psi at 28 days.
Highstrength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normalstrength concrete, highstrength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.

It persists as a specified test because in the early years of cement manufacture, it used to be the most common test since it was difficult to find machines that could compress a cement sample to failure. Today, tensile stresses are typically measured indirectly by one of two means: a splitting tension test or a flexural strength test.
