- Benefits of Precast Concrete
of precast concrete gradually
increase over time. Other materials
can deteriorate, experience
creep and stress relaxation,
lose strength and/or deflect
over time. The load-carrying
capacity of precast concrete
is derived from its own structural
qualities and does not rely
on the strength or quality of
the surrounding backfill materials.
shown that precast concrete
products can provide a service
life in excess of 100 years.
For severe service conditions,
additional design options are
available which can extend the
life of the precast concrete
product. This is extremely important
when calculating life-cycle
cost for a project.
products can act as effective
barriers to vehicular traffic
due to their size and weight.
In the current world climate,
precast concrete products such
as planters, bollards and highway
barriers increasingly are being
used to provide protection for
a wide variety of venues.
Precast concrete is resistant
to most substances. However
no material is completely immune
to attack form aggressive chemical
agents. Thus it is wise to choose
the material with the longest
expected service life. Precast
concrete products can be designed
to withstand anticipated corrosive
precast concrete products typically
are produced in a controlled
environment, they exhibit high
quality and uniformity. Variables
affecting quality typically
found on a jobsite-temperature,
humidity, material quality,
craftsmanship are nearly eliminated
in a plant environment.
Unlike some other materials,
precast concrete does not degrade
from exposure to sunlight. This
is extremely beneficial for
water, concrete is the most
frequently used material on
earth. It is nontoxic, environmentally
safe and composed of natural
materials. Buried throughout
the world, precast concrete
products help convey water without
contributing to poor water quality.
concrete is well-suited for
exposure to all types of weather
Weather Dependency Precast
increases efficiency because
weather will not delay production.
In addition, weather conditions
at the jobsite do not significantly
affect the schedule. This is
because it requires less time
to install precast compared
with other construction methods,
such as cast-in-place concrete.
Precast concrete can be easily
installed on demand and immediately
backfilled there is no need
to wait for it to cure.
sealants are specially formulated
to adhere to precast concrete,
making watertight multiple-seam
precast concrete structures
Ease of Installation Since
precast products are designed
and manufactured for simple
connection, many components
can be installed in a short
the modular nature of many precast
concrete products, structures
of systems of nearly any size
can be accommodated.
products arrive at the jobsite
ready to install. There is no
need to order raw materials
such as reinforcing steel and
concrete, and there is no need
to spend time setting up forms,
placing concrete or waiting
for the concrete to cure.
products are both functional
and decorative. They can be
shaped and molded into an endless
array of sizes and configurations.
Precast concrete can also be
produced in virtually any color
and a wide variety of finishes
(acid-etched, stand blasted,
to achieve the desired appearance
for building and site applications.
Precast concrete requires little
or no maintenance, which makes
it an ideal choice for nearly
any design solution.
Precast concrete is noncombustible.
Also, concrete does not lose
its structural capacity nearly
s quickly as steel. Other materials
besides concrete and steel are
flammable and / or do not perform
well in elevated temperatures.
