I've been have been done some research about Einstein Field Equations and I want to get great perspective of Ricci tensor so can somebody explain me what Ricci tensor does and what's the mathmatical value of Ricci tensor.

You will find a pretty decent explanation at http://math.ucr.edu/home/baez/gr/

It is simply a contraction of the Riemann tensor, in fact it is the only contraction that really makes sense because of symmetry constraints.

By the way trying to assign physically measurable properties to a tensor is questionable, at least in my mind.
