Setting time, optimal duration for the best solidification of the cement. Soundness, ability by the cement having maximal withstanding external forces or pressure exerted on to the finished concrete. Tensile strength, its flexibility to accommodate rupturing or cracking. And consistency of the cement to show uniformity, smoothness and upholds in the particles as final concrete.

By which equipment, the tensile strength for concrete cube is carried out?
Shekhar said:

But we are not performing tensile test on mortar cube. Other three answers are correct. I'm confused about Tensile strength.

Soundness test is carried out to know the increase in volume of concrete after setting. For OPC, the maximum soundness value is 10mm.

@Madhumita.
OPC means ordinary portland cement.
And mpa means megapascals = 1N/mm2.
OPC means ordinary portland cement.
And mpa means megapascals = 1N/mm2.

But why the answer is all the above. I mean why we need to test tensile, soundness, ect?

OPC means ordinary portland cement.
mpa = n/mm2.
mpa = n/mm2.

Truly, for a concrete to be attested for maximum strength all the test should be performed.
