Annual
world-wide production of concrete is over 5 billion cubic yards
A
ten-year study of 2000 miles of municipal streets in Kansas revealed that
asphalt pavement was nine times more expensive to maintain than concrete.
Concrete also proves safer due to better traction.
The
first concrete street was built in 1891 in Bellefontaine, Ohio and is
still in service today.
Due
to a smoother surface of less resistance, concrete highways are
fuel-efficient, reducing fumes and saving fuel.
Concrete
is composed of water, cement or lime and an aggregate such as sand
or gravel and was used in this basic form for decades, back to Roman
times.
Each
year, more than 4700 pounds of concrete is produced per each person in the
United States. |
Because
of concrete's light color, it reflects much of the sunlight. This concrete benefit has been shown to lower a city's
average temperature by several degrees and improves night driving on
highways.
Concrete
is environmentally friendly in many ways: the ingredients are in abundant
supply, quarries can easily be reclaimed for further usage and concrete is
an ideal product for recycling waste or commercial byproducts.
Concrete
homes boast energy efficiency, sound proofing and pest control. Concrete
doesn't burn or rot.
The
average American house contains 120,528 pounds of concrete.
Twice
as much concrete is used in construction around the world than the total
of all other building materials, including wood, steel, plastic and
aluminum.
