Over the last several decades, there
have been advancements in shotcrete technology and improvements in the equipment
that have resulted in a material that is perfectly suited for more and more
applications. While shotcrete virtually eliminates
the forming process, it still offers the same structural characteristics as
traditional cast-in-place walls. This
means that projects using shotcrete are typically completed faster, which saves
both time and money.

Some of the Methods Used to Increase the Strength of Concrete
The strength of concrete can be
increased by a number of methods including using a higher grade of cement or a mineral
admixture such as ground granulated blast furnace slag (GGBS). It can also be strengthened by using a low
water to cement ratio (W/C) as well as by using well-graded angular aggregates.

Heavyweight Concrete has Many Uses Including as a Sound Barrier
While
there are many applications in which lightweight concrete is the most
appropriate choice so are there as many that require heavyweight concrete. Lightweight structural concrete is made using
lightweight coarse aggregate and/or lightweight fine aggregate. It typically has a density of approximately
105 pounds per cubic foot as compared to that of normal concrete mixes that
have a density of 150 pounds per cubic foot.
A common use for lightweight concrete is to reduce the overall load or
weight of an entire concrete structure such as on bridge decks, beams, slabs
and walls of concrete structures.

The US Cement Industry
Cement
is the key ingredient in concrete, and as the Portland Cement Association (PCA)
explains, portland cement is “the generic term for the type of cement used in
virtually all concrete, just as stainless is a type of steel and sterling a
type of silver.” To manufacture cement,
lime, silica, alumina, iron and other materials are heated to extremely high
temperatures that create marble-size balls or nodules called clinker. Next the clinker is ground up and mixed in
with limestone and gypsum.

New Salesforce Videos
One of the big projects The Conco Companies recently provided a full range of concrete services for was the
Salesforce Tower in downtown San Francisco.
Now that the silvery curtain-wall panels have completely covered the
outside of the 1,070-foot tall building, it can be seen for miles in and around
San Francisco. This is probably not
surprising as the peak of the building stands 200 feet taller than the city’s
previously tallest building, the Transamerica Pyramid. The 61-story building consists of 900 feet of
occupied space with spacious office floors that boast ceiling heights of almost
14 feet. The remaining 170 feet above
the top floor of the building is mainly empty space but does house some
mechanical equipment.

The World’s Fastest Elevators and Longest Elevator Runs
The Council on Tall Buildings and
Urban Habitat (CTBUH) recently published a report in collaboration with the
Guinness Book of World Records on the fastest elevators and the longest
elevator run in skyscrapers. It evaluates
elevators in commercial buildings from across the globe to determine the speed
and the length of their run. The CTBUH
has certified the Shanghai Tower, currently the world's second-tallest building
at 632 meters tall (2,073′), takes the prize for both the “fastest elevator and
the longest elevator run of all commercial buildings in the world.”
