The earliest material for construction was either stone or plaster, and most modern materials in our opinion is precast concrete. While concrete may appear unfinished, it can be finely finished and make most beautiful buildings in the world. While precast concrete often serves a very functional infrastructure, it makes modern comforts possible, adds beauty to function, and durability to our environment.

1. Precast Concrete

2. The
earliest
materials
for
construc1on
was
either
stone
or
plaster,
and
most
modern
material
in
our
opinion
is
precast
concrete.
While
concrete
may
appear
unfinished,
it
can
be
finely
finished
and
make
most
beau1ful
buildings
in
the
world.

3. The
tallest
building
that
uses
precast
concrete
is
the
Transamerica
Pyramid
in
the
San
Francisco
skyline,
stands
at
850
C.
(260
m.).

4. Another
example
is
Park
Tower
in
Chicago
which
rises
844
C.
(257
m.),
it
is
the
second
tallest
building
in
the
U.S.,
to
be
clad
in
precast
concrete.

5. Concrete
is
essen1ally
a
combina1on
of
stone
chips,
gravel,
sand,
water,
various
admixtures
and
cement.
When
water
is
added
to
cement,
it
causes
a
chemical
reac1on
that
binds
various
other
components
of
concrete
together,
and
makes
the
product
stronger
than
stone.

6. Concrete
is
weak
in
tension
hence
its
ability
to
crack.
You
can
reinforce
concrete
with
steel
and
let
the
steel
take
the
tension.
The
end
result
is
that
you
acquire
stronger
and
versa1le
building
material.

7. Precast
concrete
is
used
to
save
1me,
and
there
is
no
need
to
wait
for
lower
floors
of
a
structure,
to
cure
before
adding
on
higher
levels.
Panels
can
be
cast
ahead
of
1me
and
then
added
when
needed.

8. Precas1ng
concrete
are
produced
in
factory
under
controlled
condi1ons
such
as
temperature
and
humidity,
because
it
can
have
a
huge
impact
on
concrete
curing
and
strength
of
the
panels.

9. Intricate
designs
can
be
cast
into
precast
panels,
and
various
finish
like
stone
or
others
can
be
added
to
the
precast
panels.
While
precast
concrete
oCen
serves
a
very
func1onal
infrastructure,
it
makes
modern
comforts
possible,
adds
beauty
to
func1on,
and
durability
to
our
environment.
