stress in old concrete
The ratio of cement, sand and crushed stone in M 25 grade concrete is 1:1:2.In this grade of concrete a compressive strength not less than 25 N/mm2 is achieved in 28 days.
25 Yards of concrete
The Civil Engineering Data Standards manual states the density of many grades of concrete. Standard density for fresh M-25 concrete is: 2414 Kg/ M3.
The density of reinforced concrete is 2500 kg/cum or 25 kn/cum
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4
weight of 1 cubic mitre of concrete

how may yards of concrete are needed for a floor 24 x 25 feet?
That depends on the length and width of your construction.
25 Yards of concrete
They're talking about compressive strength - the amount of force that can be applied to a defined area of the concrete before it fails. 25 MPa concrete in the states would be 3625 psi concrete - very ordinary stuff; the kind in bags at Home Depot is stronger than that.
