1 - First of all raw material will be as per design (good quality).
2 - Concrete mixing is important.
3 - Slump test.
4 - Water Cement Ratio.
5 - Carry out the machine to place.
6 - Placing and vibrator.
7 - Time sitting.
8 - Curing.
9 - Compression test.
10 - Fall of height.
11 - Cube or cylindrical test.
12 - Consistency.

Tensile strength does not consider at concreting member design.

All the above.
Because the setting time, soundness is very important.

In basic think, cement should have a binding property, so the quality control depends upon the compressive strength only. So, the compression test is enough.

As per design. Usually the class of A1 is 1500 psi and A2 is 2500psi.

To prepare concrete with portland cement we must know the characteristic compressive strength within the span of 7days and 28 day curing.

At the time of bleeding, water comes out of the surface of concrete being lowest specific gravity among all other ingredients.
