Concrete strengths are customarily denominated in psi(pounds per square inch) in the imperial system and in MPa's(megapascals) in metric. These are units of pressure.

What is the compressive strength of M40 concrete?
40 MPa
A procedure for mixing 25MPa concrete with a small 180l concrete mixer without additives?
Proportions for different grades: Cement : Sand : Gravel 1 : 2 : 5 for grade C15(general purpose concrete) 15 mpa 1 : 2 : 4 for grade C25(strong) 25 mpa 1 : 2 : 3 for grade C30(very strong) 30 mpa Remember the proportion is done in terms of volume. This means the above proportions are correct if using the same measure.
What is the meaning of C10 concrete?
what is meaning of concrete 10
What does it mean if you measure concrete strength to be 50 MPa?
The units of Mpa is N/mm2 so this means that the concrete can resist a compresion forse of 50 newtons spread over 1 mm2 *Note if this value is a measured value a safety factor needs to be applied if it is to be used in construction, this factor are specified in you country's design code
What is the yield strength of plain concrete?
The yield strength in this case is equal to the ultimate tensile strength, which is about 0.9-3 MPa without any reinforcement.
What is 30 MPA?
the strength of concrete
Which grade of concrete is used in pre-tensioned prestressed concrete structure?
42 mpa for pre tension and 35 mpa for post tensioned
What what mpa strength is baged premixed concrete?
Bagged Premixed Concrete will achieve an mpa strength of around 20 mpa and is usually expected to reach this at 28 days. The "Rapid Set" Premix Bagged products are only good for about for about 5 mpa. .
What is the compressive strength of M40 concrete?
40 MPa
What does 25 mpa concrete mean?
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.
What is the price of one cubic meter of 30 Mpa Concrete?
700 rubles.

What is unit weight in kg of rebars per 60MPa of one cubic meter of reinforced concrete?
It is about 150 to 180 kilograms per cubic meter of 60 MPa concrete
What is high strength concrete?
Concrete with compressive strength more than 55 MPa is known as high strength concrete.It is used in the construction of bridges, dams. etc.,High strength concrete is produced by adding normal constituents of concrete with admixtures.
What is the meaning of C10 concrete?

What is the wet unit weight of concrete?
unit weight= weight/volume.unit weight of normal concrete = 24 MPaIt is also known as density of concrete
What is the meaning of 2.5 MPa?
2.5 mega pascals2,500,000 N/m^2
