Concrete is the most widely used construction material in India with annual consumption exceeding 100 million cubic meters. High performance concrete is a concrete in which certain characteristics are developed for a particular application and environment, so that it will give excellent performance in the structure in which it will be placed. A high-strength concrete is always a high performance concrete, but a high-performance concrete is not always a high-strength concrete.

4. INTRODUCTION
 Concrete is the most widely used construction material in India
with annual consumption exceeding 100 million cubic meters.
 High performance concrete is a concrete in which certain
characteristics are developed for a particular application and
environment, so that it will give excellent performance in the
structure in which it will be placed.
 A high-strength concrete is always a high performance concrete,
but a high-performance concrete is not always a high-strength
concrete.

5. What is High Performance Concrete ?
 According to Paul Zia
HPC is a concrete, which meets special performance, and
uniformity requirements that cannot be always achieved by using
only the conventional materials and normal mixing, placing, and
curing practices.
According to Civil Engineering Research Foundation (CERP)
HPC is a concrete in which some or all of the following properties
have been enhanced.
(a) Ease of placement
(b) Long term mechanical properties
(c) Early age strength
(d) Toughness

6. Components/Ingredients
The main ingredients of HPC are as follows
1) Cement
2) Fine aggregate
3) Coarse aggregate
4) Water
5) Mineral admixtures (fine filler and/or pozzolonic supplementary
cementitious materials)
6) Chemical admixtures (plasticizers, superplasticizers, retarders, air-
entraining agents)

7. Methods for achieving High Performance
 Better durability performance has been achieved by using high-
strength, low w/c ratio concrete.
Two approaches to achieve durability through different techniques
are as follows
(1)Reducing the capillary pore system such that no fluid
movement can occur is the first approach. This is very difficult
to realize and all concrete will have some interconnected pores.

8. 2. Creating chemically active binding sites which prevent
transport of aggressive ions such as chlorides is the second
more effective method. There are two approaches are shown
in Fig.1

9. Characteristics of High performance concrete.
Concrete may be regarded as high performance for several different
reasons:
 Very low porosity through a tight and refined pore structure of the
cement paste.
 Very low permeability of the concrete
 High resistance to chemical attack.
 Low heat of hydration
 High early strength and continued strength development
 Low water binder ratio
 Low bleeding and plastic shrinkage

10. Stress-strain Behavior
 The shape of the ascending part of the stress-strain curve is more
linear and steeper for high-strength concrete, and the strain at the
maximum stress is slightly higher for HPC.
 The slope of the descending part becomes steeper for high
performance concrete.
 High performance concrete exhibits less internal micro cracking than
lower-strength concrete for a given imposed axial strain.

11. Advantages
 Speed Of Construction
 Economical Material In terms Of Time And Money
 Higher Seismic Resistance
 Improved Durability
 Abrasion Resistance
 High Tensile Strength
 Reduced
 Maintenance Cost

12. Disadvantages
 An Extended Quality Control
 Cost
 Special Constituents
 Manufactured And Placed carefully

13. Application
 In Pavements
 High Performance concrete is being increasingly
used for highway pavements due to the potential
economic benefits
 Fast track concrete paving (FTCP) technology can
be used for complete pavement reconstruction.

14.  In Bridges
 HPC is being extensively used now for the fabrication of precast
pylons, piers, and girders of many long span bridges in the world
For Example The Normandie Bridge in France (1993),
 Concrete structures are preferable for railway bridges to
eliminate noise and vibration problems and minimize the
maintenance cost.
Fast track concrete paving (FTCP) technology can be used for
complete pavement reconstruction.
Application

15.  In High-rise Buildings.
 The reasons for using the high strength concrete in the area of
high-rise buildings are to reduce the dead load, the deflection,
the vibration and the noise, and the maintenance cost.
Application
 Miscellaneous Applications.
Fiber reinforced concrete has been used with and without
conventional reinforcement in many field applications. These
include bridge deck overlays, floor slabs, pavements and pavement
overlays, refractories, hydraulic structures, thin shells, rock slope
stabilization, mine tunnel linings and many precast products.

19. Conclusion
We are going to expect concrete that is a little more expensive per
cubic meter to buy but
It will require less skill and effort to place.
It will look better with no appearance defects.
It will be more durable.
It will require more skill at the batching plant.
