Welcome to the Concrete Jungle
As the title suggests, we live in a world which is now very commonly referred to as a “Concrete companies“. This term is usually seen in a negative light, as it implies ruining our forests in the process of making everything concrete. But, development is a natural process and change is inevitable. If a balance between urbanisation and restoration of our forests is maintained, the term “concrete jungle” will surely not been seen in bad light.
Frankly, it is now nearly impossible to imagine our lives without walls, pavements, foundation, roads, dams, pipes, fences, as well as boats. The common factor between all these facilities provided to us is that they are made of concrete. Its usage in the world is second only to naturally occurring water. Thorough mixture of concrete is essential for its use, for which various mixers and equipments have been and are being manufactured usually within 100 km of the job site.
A concrete mixer is equipment designed to combine cement, sand or gravel, water and concrete. It consist of a revolving drum which does the mixing job (for a lesser volume portable mixers are used), making it easier for the construction workers to use the concrete long before it dries and hardens. In today’s market, there are three kinds of concrete mixers widely available: twin-shaft mixers which are intensive mixers done in less time and are used for high strength concrete. For smaller batches used for pre-stressed concrete, vertical axis mixers are usually used, whereas, for large volumes of concrete (buildings, dams, and roads) drum mixers are utilized.
There are sometimes variations in the standard concrete transport, which is a concrete mixer trailer. These concrete mixer trucks are used to supply short loads of concrete mixtures usually in rental yards and building material location where the mixed supply is easily available to their regular customers.
Concrete pumps on the other hand are machines which are used to transfer the mixed concrete through pumping. They are of two kinds, the first one being the trailer-mounted boom concrete pump as it uses a remote controlled robotic arm (called boom) to place the concrete at the exact place where it is required. This kind of concrete pumping machine is used at large construction projects as they pump at an extremely high intensity and the robotic arm saves the usage of manual labourers.
