how much tensile strength of M20 grade concrete at 28 Days
Concrete with a grade of M10 typically has a compressive strength of around 2500 psi. This mix generally consists of a ratio of 1 part cement, 3 parts sand, and 6 parts aggregate (1:3:6). M10 is considered a low-strength concrete, often suitable for non-structural applications such as leveling or bedding. For higher strength requirements, higher-grade mixes like M20 or M25 would be more appropriate.
The strength of M20 concrete for 7days will be 63%( say 12.6) of 28days strength i.e. 20N/sq mm
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
The strength of concrete is typically measured in pounds per square inch (psi) and can vary depending on the mix and curing conditions. Common concrete strengths range from 2,500 psi for residential applications to over 5,000 psi for more demanding structural uses. High-performance concrete can achieve strengths of 10,000 psi or more. The specific strength required depends on the intended application and structural requirements.
A concrete strength of 3500 PSI should be just right for a basketball court.
M20 give you strength of 20Mpa and M25 give you strength of 25 Mpa after 28 days of curing.

it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....
The strength of M20 concrete for 7days will be 63%( say 12.6) of 28days strength i.e. 20N/sq mm
does not exceed 30N/mm2

fy= 4000 to 4500 psi
The grade of concrete refers to its compressive strength measured in megapascals (MPa) or pounds per square inch (psi) after 28 days of curing. Common grades include M15, M20, M25, and so on, where the number indicates the characteristic strength of the concrete mix. Higher-grade concrete has a greater strength, making it suitable for structural applications requiring durability and load-bearing capacity. The selection of the appropriate grade depends on the specific requirements of the construction project.
concrete and cement
The mean grade of M20 concrete is defined by its compressive strength of 20 MPa (megapascals) at 28 days. This grade typically consists of a mix ratio of 1 part cement, 1.5 parts sand, and 3 parts coarse aggregate by volume. M20 concrete is commonly used for structural applications where moderate strength is required, such as in beams, slabs, and columns.
