newton mean in concrete it is used for bearing for exemple mark
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
Probably reinforced concrete i.e concrete with metal rods (re-bar) run through to give it tensile strength as well as compressive strength.
The tensile strength of concrete is 10% of it's compressive strength.
the moisture of concrete is main strength for reinforced concrete structure
how does the fineness modulus of aggregate affect the strength of concrete
If you mean force, the SI unit is the newton. If you mean the strength of a material - its ability to withstand force - there are different types of strength: look up Compressive strength, Tensile strength, Shear strength. For example, the units for tensile strength are newtons / square meter.
it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....

Yes, the characterisrtic strength of a concrete is the same as the compressive strength
the moisture of concrete is main strength for reinforced concrete structure
tensile strength is approximately between .08 to .15 of compression strength in 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.
To calculate the target mean strength for concrete, you first determine the desired characteristic strength (fck) based on design requirements. Then, account for a specified margin of safety, typically using a standard deviation from previous test results to establish the target mean strength (fct). The formula commonly used is: Target Mean Strength = fck + 1.64 × standard deviation, where 1.64 corresponds to a 95% confidence level. This ensures that the concrete produced will meet the required strength with a high degree of reliability.
C35 concrete refers to a specific grade of concrete that has a characteristic compressive strength of 35 megapascals (MPa) when tested at 28 days. The "C" indicates that it is a concrete mix, and the number signifies its strength classification, which is commonly used in construction to ensure the material meets structural requirements. This grade is suitable for various applications, including structural elements and pavements, where higher strength is necessary.
