IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2. The mixes of gr...
GRADE: C15 CONCRETE. Strength: 15 Newtons after 28 days. An ideal concrete mix for floor blinding and kerb mix. GRADE: C20 CONCRETE. Strength: 20 Newtons after 28 days. Concrete at this strength is often applied on domestic floors and foundations where the weight of overall structures on the concrete will be lighter.
Concrete Grades. Concrete grade is defined as the minimum compressive strength rating of a mix 28 days after it was poured. Different construction projects will require concrete of certain strength ratings, so understanding the difference between concrete grades is key to finding the ideal mix for your specific requirements.
The mechanical properties of concrete are dependent on many factors, such as the characteristics of the raw materials used, the curing conditions and the local concrete practice, which may vary from place to place. The mechanical properties measured in other places cannot be directly applicable to Hong Kong.

The concrete mix ratio refers to the proportional relationship between the various constituent materials (cement, water, sand, stone) in concrete. There are two ways to express: one is the amount of various materials in 1 cubic meter of concrete, such as 300 kg of cement, 180 kg of water, 690 kg of sand, and 1,260 kg of stone; the other is the ...

Sep 03, 2019· The reason you can't find a prescribed mix ratio for C40 is it doesn't exist. BS5328 only goes up to 25N and anything above 20N can't be mixed with all in ballast. That's not to say you couldn't end up with a mix higher than 25N - just that it's not predictable based on the mix ratio. The only way to guarantee 40N is readymix.
