High-strength concrete is typically used in the erection of high-rise structures. It has been
used in components such as columns, shear walls, and foundations. High strengths are also
occasionally used in bridge applications as well. A high-rise structure suitable for highstrength concrete use is considered to be a structure over 30 stories. It is estimated that a 50story structure with 4-foot diameter columns using 4000 psi concrete can reduce column
diameters by approximately 33% by using 8000 psi concrete (Peterman).

When High-Strength Concrete is Necessary:
High Load-Bearing Requirements:
High-strength concrete is typically paired with high-strength
steel in buildings designed to carry large loads, such as highrise structures, bridges, or industrial facilities. The higher
compressive strength of the concrete complements the tensile
strength of the steel, allowing for a more efficient and
compact design.
Slimmer Structural Elements:
High-strength concrete enables the design of thinner columns,
walls, and beams, which can save space and reduce the selfweight of the structure, especially in tall buildings.

When High-Strength Concrete is Necessary:
Compatibility with High-Strength Steel:
In reinforced concrete, the interaction between steel and
concrete (bond strength) is critical. High-strength steel may
benefit from the use of higher-grade concrete to maintain a
balanced design and ensure adequate bonding.
Durability in Harsh Environments:
High-strength concrete often has lower permeability, making it
more resistant to aggressive environmental conditions like
corrosion, freeze-thaw cycles, or chemical attack, which
complements the durability of high-strength steel.

The major reasons for using High strength concrete (HSC)
for construction are:
1. Provision of greater strength for a smaller volume of
building materials used, thus saving the transportation cost.
2. Beams and columns are designed in smaller dimensions in
comparison to normal strength cement, thus saving extra
open area for the superstructure.
3. Taller buildings are safely possible only with HSC.
4. In case of roads and bridges, HSC is very beneficial for quick
setting (and thus swift readying for the traffic) and also
compatible with the increasing traffic.
5. Heavy structures like dams, bridges, embankments, etc. can
be built in smaller dimensions using HSC, since the required
strength is achieved in relatively smaller quantity of
