Definition of Concrete Mix Design:
Concrete is generally classified as Normal Strength Concrete (NSC). High Strength Concrete (HSC) and Ultra High Strength Concrete (UHSC). Indian Standard Recommended Methods of Mix design denotes the boundary at 35 MPa between NXC and HSC. They did not talk about UHSC. But elsewhere in the international forum, about thirty years ago, the high strength table was applied to concrete having strength above 40 MPa. More recently, and the threshold rose to 50 to 60 MPa. In the modern batching plants high strength concrete is produced in a mechanical manner of course, one has to take care about mix proportioning , shape of aggregates, use of supplementary cementitious materials, silica fume and super plasticize-rs. There are special methods of making high strength concrete. They are given below.
Here we are giving information about the percentage compressive strength of concrete.
It is obtained by mixing cementitious materials water and aggregates and admixtures in required proportions. The mixture when placed in forms and allowed to cure hardens into a rock like mass known as concrete.

- Seeding
- Re-vibration
- High Speed Slurry Mixing
- Use of Admixtures
- Inhibition of Cracks
- Sulphur Impregnation
- Use of Cementitious Aggregates
Application of High strength concrete:
It is used for tall buildings and
large-span bridges, it is clear that use of high-strength leads to reduce
column sizes and beam depths. In additions in results in improved performance
in terms of creep, shrinkage and other elastic proprieties that yield a more
favorable deformation pattern for tall buildings.
The improved elastic
properties also limit the reduce elastic shortening and other secondary
effects. Hence, high-strength concrete has found application in various
structures used by various industries. The application of high-strength
concrete in different industries around the world. Here we are giving information about the percentage compressive strength of concrete.
