The Conco Companies initially started out as a concrete contractor but as our business expanded over the years, we have evolved into a full service provider to the construction industry. We now provide a range of “concrete solutions” to our customers as opposed to “concrete services,” and we have the resources and expertise to oversee the entire process.
The range of services we provide include rebar fabrication and installation, concrete pumping, formwork, shotcrete, cellular concrete, trucking, design/build, general contracting and turnkey solutions. By providing such a broad array of comprehensive solutions, it creates value to all those involved in the project and has given us many loyal customers. For many projects, we believe that design/build creates the best value for our client. When Conco has early input into the design process, it typically allows us to create a better finished product and at a lower cost. This is due to the fact that we have experience with multiple means and methods for constructing similar structures and understand their unique advantages and disadvantages. We also work with engineers that value our input and factor in constructability issues into their design process. Moreover given our decades in the industry, we have extensive local knowledge of the market and understand the capabilities of suppliers and costs associated with various alternatives. Another advantage to working with Conco is we are one of the few concrete contractors on the West Coast that services both concrete and rebar. This means there is no need for schedule coordination as we control the whole process, which results in less work stoppages and delays.

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.
To help move and place concrete efficiently, concrete specialists add more water to the mix than what is strictly necessary to hydrate the cement materials. Once the concrete is placed, the excess water begins to separate from the hardening concrete, which results in a loss of volume that causes the concrete to shrink. As the concrete’s reinforcement or base friction works to restrain it, the tensile stresses in the slab cause the cracks. Since shrinking is one of the inherent properties of concrete, it is impossible to totally eliminate cracking but it can be controlled. This is the job of concrete contractors and engineers who strive to understand and address the volume change that takes place in the concrete in order to reduce the amount of shrinkage. The PCA explains that, “The shortening of concrete slabs can be caused by temperature decreases or moisture loss. These two causes are also related to curling and warping of slabs, respectively. Curling is the deformation of the slab due to a difference in temperature between the surface and the bottom of the slab (temperature gradient). Slab “warping” is the deformation of the slab surface profile due to a difference in moisture between the surface and bottom of the slab (moisture gradient),” To help solve the shrinkage problem, contractors take care to use the proper concrete mix design that will require the least amount of water as well as use the largest size of aggregate appropriate to the job. Contractors especially watch for fluctuating temperatures during the first 24 hours after the concrete is placed.

Sources: concretenetwork.com/concrete/concrete_cracks/preventing_concrete_cracks.htm cement.org/cement-concrete-applications/cement-and-concrete-basics-faqs/lists/technical-information/concrete-cracking 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.
With new materials being used in the production process, changes in the mixture’s proportions, and increased recycling efforts, concrete’s environmental impact has been reduced and durability improved. AggregateResearch.com states that, “new concretes have better corrosion resistance, equal or higher compressive and tensile strengths, higher fire resistance, and rapid curing and strength gain. In addition, the production and life cycle of these new concretes will reduce greenhouse gas emissions by as much as 90%.” High Performance Concrete (HPC), Ultra-High Performance Concrete (UHPC), and geopolymer concrete are new types of concrete mixtures that offer several advantages over traditional concrete with few disadvantages. For example HPC and UHPC are produced using industrial waste by-products such as fly ash, blast furnace slag, and silica fume. The addition of these by-products reduces the amount of portland cement required in the mix, which in turn, cuts down on the amount of carbon dioxide emitted during the production of the cement. Also there are an abundance of the by-products and are typically less expensive than portland cement. Other advancements in the industry include producing fiber reinforced concrete, which is premixed with dry components to create higher tensile and flexural strengths than found in standard concrete. Fiber reinforcement can be done with steel fibers, glass fibers, synthetic fibers and natural fibers and is less expensive than hand tied rebar.

Since 1975, we have owned and operated one of the largest concrete pumping and belting companies in the U.S., and have the capability and resources to handle the most challenging project specifications.
Our highly maneuverable concrete boom pumps provide access to areas on the jobsite that would otherwise be difficult to get including tight, confined spaces. The long reach of Conco’s boom pumps such as our Schwing S 58 SX with a vertical reach of 187’9″and horizontal reach of175’1″, offers solutions for efficiently placing concrete on high-rises and other large-scale projects. By using the appropriate boom pump for each job, our crews can place concrete not only faster but with more precision. Pumped concrete requires less handling as the pump places it directly where it is needed and allows a project to be completed much more cost-effectively. Furthermore, as placement is so accurate, it produces a more professional outcome and typically results in fewer delays. Another time-saving aspect to using large boom pumps is the job requires fewer smaller pieces of equipment. This saves time by eliminating the need to move the smaller machinery around the jobsite and then having to set it up again. Pumped concrete also offers better quality control and produces a more durable and stronger finished product. As pumped concrete requires less water, it helps prevent or mitigate shrinking and cracking problems that are common in concrete. Lastly pumped concrete is not as affected by weather conditions as other methods that often result in work stoppages and delays. Please visit our website to view the broad range of projects Conco has had the honor to serve as the placement specialist. In addition to concrete pumping we also provide concrete reinforcement and installation, formwork, shotcrete, construction hauling, and design/build and G. C. services.

Our success has come from offering clients the best value on a wide range of concrete services and products and we are now one of the region’s top commercial concrete contractors. We currently serve the areas of Southern and Northern California, Oregon, Washington Colorado, and Nevada. Portland cement is the most common type of cement and typically originates from limestone. It is the key ingredient in concrete, mortar and stucco and used throughout the world. When added to concrete, it is the paste that binds the aggregate (consisting of gravel and sand) with the water.
Defined as hydraulic cement (cement that not only hardens by reacting with water but also forms a water-resistant product), it is “produced by pulverizing clinkers consisting of essentially hydraulic calcium silicates, usually containing one or more of the forms of calcium sulfate as an inter ground addition.” The concrete mix’s strength depends on the reaction of the calcium silicates with the water. The Portland Cement Association explains that, “Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.” To produce portland cement, raw materials such as limestone, shell, or chalk are combined with clay, silica sand, shale, bauxite, fly ash, slag and iron. This mixture is heated in huge cement kilns at temperatures as high as 2,700 degrees Fahrenheit. A dark grey nodular about the size of a marble called a clinker is produced from the extreme heat and is ground into a fine powder to make the cement. Once it has cooled, a small amount of gypsum may also be added to control the setting process. Portland cement is thought to be the invention of Joseph Aspdin, a bricklayer from England, and named for its similarity to a common building stone found on the Isle of Portland in Dorset, England. Aspdin experiments were conducted in his kitchen stove where he fired ground limestone and clay together to create the first artificial cement. His new cement was a much stronger material than the standard unfired crushed limestone used during that period of time.

Sources: en.wikipedia.org/wiki/Portland_cement, cement.org/cement-concrete-basics/how-cement-is-made One of the mysteries that continue to baffle scientists and engineers is how the ancient Romans produced the strongest concrete in the world. Typically modern concrete buildings last about 50 to 60 years while ancient Roman concrete structures have survived through 2,000 years of environmental damage.
We know that the formula used to produce the ancient concrete is unique but no one knows for sure why it is so durable, but a group of scientists thinks they may soon find some answers. Geologists and biologists will travel to the Surtsey Island in Iceland to see if they are right. Since ancient Roman concrete was made from volcanic ash and seawater, Surtsey is a good place for answers as the entire island is made of volcanic ash and seawater caused by an underwater volcanic eruption in 1963. In 1979, researchers drilled a hole 181 meters (593 feet) deep into the volcanic rock in order to study the microbial life. The hole has been monitored since it was drilled and temperatures have cooled from 140 °C to about 130 °C. On their upcoming trip they plan to drill two more holes, one that is parallel to the original hole and another at an angle. The new holes will be deeper that the one from 1979 and is expected to penetrate 190 meters (623 feet) down to the original ocean floor before the eruption. The scientists plan to study the rock and mineral formation of the volcano and try to determine what makes the volcanic material so durable. Researchers explain that Surtsey is “unique because when it formed the mixture of heat, volcanic material, and seawater created hydrothermal minerals that strengthened the rock.” The island is much more durable than other volcanic islands as the volcanic rock is less porous and almost impervious to erosion. The hope is that by analyzing the rock from Surtsey, it may provide clues to the volcanic ash that went into ancient Roman concrete.
