Mix design of special High strength concrete M60 grade concrete and its properties

Definition of Concrete Mix Design:
High-strength-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.


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.
  1.  Seeding
  2.  Re-vibration
  3.   High Speed Slurry Mixing
  4.   Use of Admixtures
  5.  Inhibition of Cracks
  6.  Sulphur  Impregnation
  7. 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.
