Topic > The Role of Concrete in the Material World for every person on Earth.[2]" this shows in short how concrete greatly affects our lives since it was invented. Concrete is one of the most commonly used building materials in the construction of different variants of infrastructure. It is made up of the following: cement which is commonly Portland cement, water, aggregates (which is made up of fine and coarse aggregates), and the use of additives which are added to the mixture immediately before or during mixing of the concrete. Therefore, the development of new materials in concrete has been widespread and thus acquires a new source of innovation in which its performance has a huge effect. The development of these new types of concrete has improved versions to place emphasis on the durability, workability, mechanical properties and also the reliability of the concrete structures to be built. Therefore, a new development from new materials means new methods in the process that can be economical and beneficial. There are various types of new methods in concrete, one of which is that allows you to build monolithic walls and slabs in one operation on a daily cycle, which is a formwork system called Tunnel Form.

Get Original EssayTunnel Form is an advanced construction method in which it is suitable for building apartment buildings, hotels, prisons, commercial developments, condominiums and other typical buildings that are built with a high degree of repetition. It is a process that uses steel and concrete forms to create an envelope composed of a series of structural tunnels. This is an operation of pouring slabs and walls in a single operation in a daily cycle, so when the process begins, the flow should be consistent with rotating shapes every 24 hours. Walls and scaffolding, which also includes the framework and plumbing, are positioned every day so that in just 3 days work can be done on the newly formed tunnel spans which can then be removed after its formation. In this method, to create an inverted U-shaped floor, walls and ceilings to form a single unit, the L-shaped units are clamped together to form a single unit. Other construction on the inside, the reinforcements are fixed, the doors and corridors are boxed and ducts and the like are installed for lighting. Pouring the concrete is the next step, the increase in strength of the concrete due to the increase in temperature accelerating; the shapes can be disassembled and repositioned the next day. The shapes are then coated in steel so that the resulting cast surfaces can be decorated. To achieve this type of method, elaborate steps, processes are provided so as to have a systematic result. According to theconstructor.org, this validates these steps as follows: The tunnel formwork forms an “L” shape that is bolted together at the top to form a tunnel. The steel used in the formwork is reused up to 600 times to produce a different variety of sizes, making this method economical. A 24-hour rotation of its construction cycle is expected. In reality, the shape of the tunnel will look like this when the two halves are bolted together: "The process of casting tunnel formwork: Please note: this is just an example.
