High-strength concrete is generally used in the shaping of high-rise structures. It has been used in components of building such as columns (especially on lower floors where the loads will be greatest), shear walls, and foundations. High strengths are also occasionally used in bridge applications as well

1. applications of high strength concrete
PAGE NO 1
 High Strength Concrete is generally used in components of
structures such as columns (especially on lower floors where the
loads will be greatest), as it decreases the column size and also
the amount of steel required
 In high rise structures High Strength Concrete increases the floor
area, reduce the column and beam dimensions.
 High Strength Concrete is benefitial economically since the
amount of floor area for rental purpose, mainly on the lower
floors, increases as the space occupied by the columns decreases
 High Strength Concrete are also occasionally used in construction
of highway bridges
 In bridges use of high strength concrete reduces the no. of beams
supporting the slab

 In joingy bridge,high strength concrete reduces the volume by 30% as
compared to normalstrength concrete
 In vidya sagar setu bridge,bcoz of useof hsc instead of nsc increases the
span between two column and strength.

2.  In high-rise structures,high-strength concrete has been successfully used in many U.S. cities. A high-rise
structure suitable for high-strength concrete use is considered to be a structure over 30 stories.Not only has
special concrete made such projects feasible due to load capacity, it has also allowed for the reduction of
column and beam dimensions. Lower dead loads result, reducing the loads associated with foundation
design.Also, owners benefit economically since the amount of rentable floor space,primarily on the lower
floors, increases as the space occupied by the columns decreases.It is estimated that a 50-story structure
with 4-foot diameter columns using 4000 psi concrete can reduce column diameters by approximately 33%
by using 8000 psi concrete (Peterman).
 High –strength concrete is occasionally used in the construction of highway bridges. High-strength
concrete permits reinforced or prestressed concrete girders to span greater lengths than normal strength
concrete girders. Also, the greater individual girder capacities may enable a decrease in the number of
girders required. Thus, an economical advantage is created for concrete producers in that concrete is
promoted for use in a particular bridge project as opposed to steel.
