The U.S. Concrete Industry



The concrete industry produces approximately 10 billion tons of concrete worldwide.  In the U.S. the industry has an annual production of 500 million tons with an estimated value of $35 billion and employs more than 2 million employees.  It is suggested that with the amount of the U.S.’s yearly production that it equals to about two tons for every man, woman and child.   To produce these types of volumes, it requires vast amounts of natural resources to supply the aggregate needed as well as to make the cement.  Concrete is used to build highways, streets and bridges, commercial, industrial, medical and educational structures, residential housing and other construction markets.

Shortages of Qualified Workers are Rampant throughout the Industry


Over the last several years, we have experienced a dwindling number of new workers seeking careers in the construction industry.  Some think this may be due to young people entering the job market feeling that construction work is not a glamorous or lucrative profession.  The problem has come to a head as older, experienced tradespeople retire and not enough people are stepping into the jobs causing a shortage in experienced cement masons, carpenters and ironworkers.

Shotcrete Projects


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.

Dealing with Concrete’s Shrinkage and Cracking Problem


Most material, including concrete, shrinks as it dries.  The Portland Cement Association (PCA) points out that the most common amount of shrinkage is about 1/16 of an inch in a 10-foot length of concrete.  To alleviate the problem, joints are placed in concrete pavement and floors “to allow the concrete to crack in a neat, straight line at the joint, where concrete cracks due to shrinkage are expected to occur.”   Likewise expansion joints are placed in bridges, concrete walls and other structures to allow for shrinkage and to control cracking.

Today’s Concrete is More Resilient


Over the last several decades, technological advancements in the concrete industry have led to improvements in both the strength of concrete as well as the longevity.  In fact, experts predict that concrete mixes of today can produce concrete that will last for hundreds of years rather than just decades of concrete structures from the 20th century.  Along with the superior performance, concrete has also become “greener” to produce.

The Importance of Curing Concrete Properly


At The Conco Companies, we have experience placing any type of concrete for a broad range of projects and in a variety of weather conditions.  Our crews use several different methods for curing concrete as it is determined by the type of construction and the concrete mix as well as outside temperatures and humidity.  Other considerations include project specifications and/or parameters of the jobsite.  However regardless of the technique used for curing, it is important to keep the concrete moist and prevent further loss of moisture.

New Fixes for Concrete Spalling


Concrete spalling and cracking, sometime referred to as concrete cancer, is caused by rebar corrosion and can affect buildings and other concrete structures.  Once the steel reinforcing in a concrete slab begins to rust, the steel rust can expand up to 7 times its original size and results in concrete being displaced and getting flakey.  As the steel pushes the concrete away, it allows more water to come into contact with the steel and compounds the problem.

Reactive Powder Concrete


Reactive Powder Concrete (RPC), which is also known as Ultra-High Performance Concrete (UHPC), is a combination of portland cement, silica fume, quartz flour, fine silica sand, high-range water reducer, water, and optional additives.  The Portland Cement Association explains that reactive powder concrete is “extremely workable, durable and yields ultra-high strengths without using coarse aggregates. Reaching compressive strengths of 30,000 pounds per square inch (psi), this new-age concrete also has tensile strength with the inclusion of steel and synthetic fibers.”   The micro structure of RPC is optimized by precise graduation of all particles in the mix to give it maximum density.

Fiber Reinforced Concrete


Fiber reinforced concrete (FRC), a type of reinforced concrete that uses a fibrous substance to increase structural strength, durability and ductility, is a subject of new research and developments.  In FRC, short, discrete fibers are uniformly distributed and randomly oriented to provide a kind of three-dimensional stability and include fibers made of steel, glass and synthetic or natural material.  Depending on which material is used, they offer varying properties and characteristics.

Tilt-up Construction Offers Several Benefits


Tilt-up construction, also known as tilt-slab or tilt-wall, is a construction technique in which concrete wall panels are cast-on-site and tilted into place.  It was first used in America around 1905, and patented in 1908 by Robert Akin during the concrete construction of the Schindler House in West Hollywood, CA.
