The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.

What is the concrete mixing ratio in C30 concrete as per British standards?

What is the differences between C30 Concrete and C40?
The number relates to the compressive strength of a cube of concrete when tested (i.e. 30 N/mm2 or 40N/mm2) The higher the number the greater the strength of the concrete. The choice of concrete grade is usually made at the design stage for the strucutre and effects the overall strength and resistance of the strucutre to decay. You would use a higher strength concrete in a more exposed environment. It is important to use the concrete grade specified for the proposed strucutre.

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 C 30 mean?
C30 typically refers to a specific type of concrete mix with a characteristic compressive strength of 30 megapascals (MPa) when tested at 28 days. It is commonly used in construction for structural applications where moderate strength is required. The "C" stands for "Concrete," and the number indicates the strength grade. This classification helps engineers and builders select the appropriate concrete mix for their projects.
What grade of concrete is laid for bed of foundation?
Full basement is the grade of concrete that is laid for foundation.
What is the difference between concrete grade and concrete strength?
concrete grade and strength are both revalent since if grade increase setting time will be less and curing to be done propely so that concrete strength will reach higher. If concrete grade is low curing to done longer days upto intial setting time to reach proper strength
