Tenorio’s Construction has grown into one of the area’s strongest commercial concrete contractors by staying focused on the demands of our clients – by helping our clients solve their problems. Listening to them while working alongside them, we have responded with a service base that meets the level of their needs – whether the project calls for turnkey construction, pour and finish, pumping or rebar placement. Years of success doesn’t happen by coincidence. It takes dedication to being the best. Our customers depend on us to deliver jobs in tight timeframes, regardless of project size. When clients call, we listen. When they ask questions, we respond. When issues arise, we don’t offer excuses – instead we face them head on.
Commercial concrete can be broadly defined as concrete used to build or enhance business facilities, such as industrial buildings, warehouses, retail stores and even restaurants. Commercial concrete can be found nearly everywhere in a building, including the walls, floors, exterior walkways and pavements, and even the architectural details. When compared with residential concrete, commercial concrete usually has greater demands placed on it in terms of structural performance and durability. Commercial concrete floors and pavements often require a stronger concrete mix design and heavier reinforcement, such as post-tensioned slab construction.
Concrete has relatively high compressive strength, but significantly lower tensile strength. As a result,[further explanation needed] without compensating, concrete would almost always fail from tensile stresses – even when loaded in compression. The practical implication of this is that concrete elements subjected to tensile stresses must be reinforced with materials that are strong in tension (often steel). The elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft).
Reinforced concrete is the most common form of concrete. The reinforcement is often steel, rebar (mesh, spiral, bars and other forms). Structural fibers of various materials are available. Concrete can also be prestressed (reducing tensile stress) using internal steel cables (tendons), allowing for beams or slabs with a longer span than is practical with reinforced concrete alone. Inspection of existing concrete structures can be non-destructive if carried out with equipment such as a Schmidt hammer, which is sometimes used to estimate relative concrete strengths in the field.
