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 else can I help you with?
What is 30 MPA?
the strength of concrete
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 two basic grades of concrete for paths and driveways?
The two basic grades of concrete commonly used for paths and driveways are standard concrete (often referred to as "normal strength concrete") and high-strength concrete. Standard concrete typically has a compressive strength of around 20-25 MPa (megapascals) and is suitable for light to moderate traffic. High-strength concrete, with a compressive strength of 30 MPa or higher, is recommended for areas that experience heavier loads or more intense wear and tear. Selecting the appropriate grade depends on the anticipated load and usage of the surface.
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 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 30 MPA?

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 is the difference between M20 and M25 concrete?
M20 give you strength of 20Mpa and M25 give you strength of 25 Mpa after 28 days of curing.
The meaning of mpa in concrete?
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.
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 price of one cubic meter of 30 Mpa Concrete?
700 rubles.
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 equivalent of c-40 concrete in to psi?
C-40 concrete has a characteristic compressive strength of 40 MPa (megapascals). To convert this to psi (pounds per square inch), you can use the conversion factor where 1 MPa is approximately equal to 145.038 psi. Therefore, C-40 concrete is equivalent to about 5,800 psi.
What is unit weight in kg of rebars per 60MPa of one cubic meter of reinforced concrete?
The unit weight of rebars is typically around 7.85 kg/m³. In a reinforced concrete mix with a compressive strength of 60 MPa, the amount of reinforcement steel used is usually between 1-2% of the total volume of concrete. Therefore, the weight of rebars per cubic meter of reinforced concrete at 60 MPa would be approximately 78.5 kg/m³ to 157 kg/m³.
