All concrete is not created equal. Just as construction projects have
different requirements, concrete can be produced with a wide variety of
characteristics. Here are just a few examples of "specialty" mixes:
Concrete is often confused with cement!
Concrete is composed of a mixture of aggregate, cement &
Various admixtures can be used to help enhance the concretes
workability, durability & strength characteristics.
Also to help control set time!
Early Concrete, or HES, develops strength faster than normal concrete.
Depending on your needs, HES Concrete can be designed to develop
sufficient strength to support vehicles in a few days, or in special
circumstances can be ready for traffic in about 7 hours. Most HES
Concrete is produced using higher cement content in the mix, and
sometimes special chemicals or "admixtures" are added to further enhance
the early strength.
concrete is normally produced by replacing the gravel or stone with a
lightweight expanded shale aggregate. This aggregate is produced by
taking shale and heating it in a kiln, which expands the shale, making
it lighter per cubic foot than normal weight aggregates. Normal weight
concrete mixes weigh about 113 to 118 pounds per cubic foot. This weight
saving makes lightweight concrete very desirable in suspended deck
slabs, such as those found in high-rise multi-story structures, allowing
the use of smaller structural columns, giving the building more useable
floor space. Lightweight concrete is also used in many bridge deck
slabs. This can allow for smaller superstructures, or in the case of
rehabilitating an older bridge, can allow for wider lanes of traffic on
the same old superstructure.
Aggregate Concrete is just that: concrete that has had its surface
removed, exposing the gravel or stone in the concrete. This method is an
economical way to produce an architectural concrete, with very unique
features. Various types and sizes of gravel or stone can be used to get
various looks. The price difference between normal concrete and exposed
aggregate concrete varies widely, depending on the type of stone used.
Utilizing readily available aggregates in your local area, such as a
river gravel, can produce very attractive results, with a nominal cost
for the extra labor involved in the removal of the surface. Give thought
when choosing the aggregate type, as a crushed stone may be visually
appealing, but it will prove quite difficult to walk on, especially in
bare feet. Check with your local concrete producer if you have any
questions, or would like the name of a qualified contractor.
concrete can give you the look and appeal of brick, flagstone,
cobblestone or many other types of finishes, at a cost far less than the
real thing. Utilizing flexible patterns and colored concrete, qualified
contractors can produce dozens of different looks. If you want something
unique and distinguished, consider stamped concrete. Your local concrete
supplier can recommend a qualified contractor to contact.
