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.
The production of cement accounts for 5 percent of manmade carbon dioxide emissions but the PCA reports that since the 1990s, the US cement industry has been “committed to minimizing emissions, waste, energy consumption, and the use of virgin raw materials. In addition concrete is a very durable product that is used to produce sustainable infrastructure that is resistant to damage from natural disasters and fire. Concrete structures are also more energy-efficient to heat and cool and concrete pavement has been shown to provide better fuel economy. The PCA cites the fact that the US cement industry employs nearly 13,800 workers and has an annual payroll of approximately $959 million. When concrete-related industries are included, the number of employees rises to 490,691 and the annual payroll is $22.5 billion. In California, The Conco Companies home base, the cement industry contributes $36.6 million to the state revenue and together the cement and concrete-related industries contribute $5.4 billion. Altogether there are 90 cement plants located in 33 states and every state in the continental US has distribution facilities. In California there are 10 plants and 11 terminals. In Washington State, another place where we provide concrete services, there are three plants and nine terminals.

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.”
The Shanghai’s elevator has a speed of 20.5 meters per second and an elevator run of 578.55 meters (1898.13). The world’s second fastest elevator speed is in the CTF Finance Center in Guangzhou coming in at 20 meters per second followed by the Tapei 101 at 508 meters tall with a speed of 16.83 meters per second. The Ping An Finance Centre has the world’s second longest elevator run of 573.5 meters which is followed by the CTF Finance Center with a run of 516.7 meters. The Burj Khalifa has an elevator run of 504 meters. Out of the world’s five tallest buildings, four of them tie (the Burj Khalifa, Shanghai Tower, Ping An Finance, and Lotte World Tower) for the fastest double-decker elevator speeds of 10 meters per second.

While not new to the area as we have performed services for Portland from our facilities in Kent, WA, this is our first actual office in the city. The need for the office made sense as we are working on several large projects throughout the city and having a more established presence allows us to better serve our current clients as well as future clients.
One of our new projects is the Modera Glisan, a 12-story mixed-use high-rise that will offer 291 residential units on the upper floors and retail and commercial space at ground level. The project also includes an underground parking garage for approximately 223 vehicles and parking for 445 bicycles. The exterior will be comprised of granite colored brick, metal panels in two colors, glass balcony railings and aluminum storefronts. Conco will be responsible for providing concrete pumping, reinforcement, formwork, finishing, shotcrete, formwork, and construction trucking. As the job requires an aggressive schedule, we will need to use multiple placing booms. Another one of our new Portland project is 14 & Glisan, a 16-story high-rise that when finished will have 230 residential units and approximately 4,285 square feet of ground floor retail space. The tower’s exterior includes pre-cast concrete panels, brick veneer, aluminum storefront glazing and a unitized window/wall system. It will also have three levels of below grade parking to accomodate 201 vehicles. Conco’s duties include concrete pumping, reinforcement, formwork, shotcrete, and finishing as well as construction trucking services. During the course of the project, we will place 16,000 cubic yards of concrete and expect the job to take us approximately 10 months.

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.
An article on the Concrete Portal website explains that Reactive Powder Concrete (RPC) is “a developing composite material that will allow the concrete industry to optimize material use, generate economic benefits, and build structures that are strong, durable, and sensitive to environment.” When researchers compare the physical, mechanical, and durability properties of RPC to HPC (High Performance Concrete), studies show RPC offering “better strength (both compressive and flexural) and lower permeability compared to HPC.” HPC is designed to be more durable and sometimes stronger than conventional concrete and is a mixture of cement, water, and aggregate as well as mineral components and chemical admixtures with specific characteristics. Achieving its maximum compressive strength, the coarse aggregate in the HPC prevents it from going further. In the case of RPC, the coarse aggregate is removed to provide the concrete with an even better compressive strength. Along with very fine powders of cement, sand, quartz powder and silica fume, a RPC mix may contain steel fibers and a superplasticizer. RPC was developed by P. Richard and M. Cheyrezy and first produced in the early 1990s in France at the Bouygues’ Laboratory. The first project to use RPC was the Sherbrooke Bridge, a pedestrian bridge in Canada.

To remain a leader, we continue to invest in new concrete pumps to provide customers one of the most modern, state-of-the-art operations on the West Coast.
To serve our customers, we have a large fleet of concrete pumps that are located in Northern California, Southern California and Washington. Our pumps are manufactured by two of the top names in the industry. Putzmeister America, Inc. is the North American division of one of the most recognized and respected manufacturers of concrete and material placing equipment. Schwing America is a member of the SCHWING Group, a worldwide designer, manufacturer and distributor of premium concrete production and handling equipment that is headquartered in Herne, Germany. All three of our pump locations have a Schwing 58SX long boom concrete pump that meets the latest emissions standards and is helping to reduce emissions at our jobsites. With a 4-Section Overhead Roll and Fold, the innovative boom design works well on bridges, commercial and industrial work and has a reach of 175 feet. The versatile boom has a main section that articulates 180-degrees, which allows it to be angled away from the pour and then guided horizontally into enclosed areas, positioned vertically for elevated work, and stretched out over the cab for flatwork. Another impressive pump we have available in all locations is the Putzmeister 36Z. With its detachable Putzmeister Z-Fold boom, the 36Z has great reach. It is the only four-section, 116-foot 10-inch boom on the market using X-style outriggers. The powerful pumping performance with a small footprint makes it perfect for restrictive job sites.
