Information needed on concrete grades and strength

[Benson Enyinda Garshon]

1) What is the Mix proportion of Self compacting concrete Grade M20, M30, M40, M50, and M60....?


2) What is the Mix proportion of Normal concrete Grade M20, M30, M40, M50, and M60....?


3) What is the Compressive strength of Concrete In 7, 14, 28, 90 days in self compacting concrete?


4) What is the Compressive strength of Concrete In 7, 14, 28, 90 days in Normal Concrete ?


5)What are there Applicability or Usuage ?

Pls, I need materials on this above
Thanks....

1) What is the Mix proportion of Self compacting concrete Grade M20, M30, M40, M50, and M60....?

Mix proportions are not something which are readily available. the cementicious content in the self compacting concrete is very high which results automatically into concrete grade of M40 +. to enable the flowability and compaction max size of aggregate used is 10mm only.

2) What is the Mix proportion of Normal concrete Grade M20, M30, M40, M50, and M60....?

do check at below section, there are some concrete mix designs posted for taking reference only
Engineered Concrete

3) What is the Compressive strength of Concrete In 7, 14, 28, 90 days in self compacting concrete?

It purely depend on the how concrete mix design is done and which parameters were considered while doing mix design, in normal concrete mixes, in general 60 to 70 % strength is achieved at 7 days, 80 to 90 % strength achieved in 14 days, 100% strength achieved at 28 days, if the admix like fly ash, ggbs etc are used then there is further more increase in strength is observed at 90 days which is 10 to 20% beyond 100%.

5)What are there Applicability or Usuage ?

of what?

SSC is not a rocket science its just a powder concrete with some amount of aggregates that too of small size.
If SCC is not designed correctly, it will have large impact on durability of structure.
