Answer / alekh
as far as high strength concrete is concerned
strength more than m50 is known as high strength concrete
... but for this we go for design mix ...for that we use
some special admixtures,super plasticizers for better
workability
( for strength more than m20 nominal mix not recommended .
Although for m 25 its composition is 1:1:2)
