The concrete contractors San Jose use this most durable of building materials to pour driveways, garage floors and patios. It is so lasting that buildings constructed of it during the time of the Roman Empire are still standing today. One example is the Roman Pantheon, which has the biggest solid dome of this material that was ever built without the use of reinforcement.
After that era, it was not often used until the eighteenth century. It became popular again during that time. It was originally applied in layers and is now combined with water and rendered into a liquid. It is poured into forms to build bridges and highways.
Often the words concrete and cement are thought to be interchangeable. However, cement is one of the components used to make the composite concrete. Other components are aggregates such as gravel or small pebbles and sand. Various proportions of these are used. Some structures require more strength and that is taken into consideration.
It was used to build the Panama Canal, the Hoover Dam and the Roman Coliseum. It can be used to erect buildings, foundations, pavements, bridges, highways, parking garages, runways at airports and an endless number of other things.
Color is added to the mix for decorative applications. Stamping, staining and polishing also add a decorative touch. Special molds can be used to make fountains, birdbaths and statues. It can be polished to look like the mirror finish found on marble.
A patent was applied for and granted to Joseph Aspdin in 1824. He referred to it as Portland cement. A type of reinforced concrete was invented in 1849 by Joseph Monier. One of the additives in it was blood, which allegedly enabled it to resist frost damage.
Just as ingredients are varied depending on the kind of cake you are baking, the proportions of the ingredients are added in different amounts depending on needed strength. The aggregate that is added to the cement consists of large chunks of gravel or crushed limestone. Sand is another additive that is used.
Water is added to the other components and they are mixed. Prior to pouring the mixture, rebar or steel is position in the forms as needed. The wooden forms hold the mixture in place as it dries and are later removed. Weight bearing structures such as bridges, skyscrapers and highway overpasses need this extra reinforcement.
In addition to water, chemicals may be added. This is done to either speed up or slow down the rate at which the mixture hardens. A skilled contractor is able to judge the optimal proportions of all additives that are appropriately used to build each type of structure.
In San Jose, the expanding and contracting that occurs in cold climates is not a necessary consideration. However, saw cuts are routinely made to allow for some changes over time. If a pour is done and it rains unexpectedly, the area must be covered to protect it as it hardens, which is also called curing.
