by using the universal testing machine, you can get the actual max load needed to fracture the hollow block and by using the formula, Compressive strength =load(lb)/Areaofcrosssection(in2) u can get the psi rating..

M25 - M40 can be used..
1 cubic metre of m25 concrete = 2 400 kg, so 2 400 / 50 = 48 bags
3000 psi concrete weighs Approx 3900 Lb/yd3
M20 give you strength of 20Mpa and M25 give you strength of 25 Mpa after 28 days of curing.
cement consumption in M-25
It is exactly 4351 psi but generally referred to as 4500 psi.
