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.”
