Answer / er.mahadir mohamed
As per is 456-2000 code book, they published exact mix
( M15 , M20 , M25 )ratio. now we are commonly adopted in
our construction industries. but ( M30, M35,M40,....M80 )
IS DESIGN MIX. its depend upon the design mixing, water
cement ratio, and other admixtures. .... my answer is M25
is stronger to give enough strent to our construction.

Answer / mahesh deo.
Strongness of Concrete is mainly depend upon the compressive strength of concrete, & M40 denoted that comp.strength is 40 N/mm2, which is great than other...so M40 is strongest concrete.

Answer / vivek
if we fix quantity of cement sand coarse aggregate by
weight and water cement ratio then it will give required
strength

Answer / sivasankar.s
M-40,M-20 At any grade of concrete depending on as per the
client requirements, but any grade of concrete curing time
7 to 28 days means the compreesive strength should be
(20n/mm2) 7 days (40n/mm2)28 days

Answer / jebaraj
We don't need mixing
proportions. we are
making our concrete into
a ball shaped, and to raise
upto 1m height and fall
down. if that's does'nt
break then that's the best
mixing and also having
high strength

Answer / peter
M40 is the strongest as it means that it will reach a targeted concrete strength of 40 N/mm2 at 28 days. M20 means that it will be designed to reach a strength of 20 N/mm2 at 28 days.
Generally, increased strengths are achieved by adding more cement, although other additives can help.
A M20 concrete cannot be theoretically be stronger than M40 as it is being designed initially for a lower strength gain; - if it achieves a higher strength than 20 N/mm2 at 28 days, then it is not really an M20 mix.
Hopefully this has clarified matters

Answer / sunil1505
M 40 but above 20 is suitable to for RCC.. depending upon
the strength we take different grades.. according
smorth...after 7 days strength 66.6 per of thate grade for
14 days 100 persent
