What is Mivan Shuttering?

Mivan Shuttering Formwork is a type of construction formwork system that is commonly used in the construction industry. It is a fast and efficient method of constructing reinforced concrete structures, particularly for high-rise buildings and large-scale projects.

The Mivan Shuttering Formwork system consists of lightweight aluminum panels, which are easily assembled and dismantled. These panels are interconnected using a series of pins and wedges, creating a sturdy and rigid framework for pouring concrete. The formwork system is designed to accommodate various shapes and sizes of structural elements, including walls, columns, beams, and slabs.

One of the key advantages of the Mivan Shuttering Formwork system is its speed of construction. The lightweight aluminum panels can be easily handled and transported, allowing for quick assembly and disassembly on-site. This helps to reduce construction time and labor costs.

Additionally, the Mivan Shuttering Formwork system provides a high-quality finish to the concrete structure. The smooth aluminum surface of the formwork panels eliminates the need for plastering or additional finishing work, saving both time and money.

Furthermore, the Mivan Shuttering Formwork system offers excellent durability and reusability. The aluminum panels are designed to withstand multiple cycles of use, making them a cost-effective solution for repetitive construction projects.

Steps In The Construction Of Mivan Shuttering

The construction of Mivan shuttering involves a systematic process to ensure efficient and accurate assembly of the formwork system. Here are the typical steps in the construction of Mivan shuttering:

Setting up the wall reinforcement steel

In the Mivan shuttering construction process, the first and foremost step is indeed setting up the wall reinforcing steel (rebar). This steel mesh is typically prefabricated in a manufacturing unit according to the shape and size of the structure, similar to precast concrete elements. Once the steel mesh is ready, it is transported to the construction site and erected in its designated position.

The steel mesh is carefully placed and secured according to the structural design. This includes positioning the rebar at the appropriate locations, such as columns, beams, and slabs, as per the specified spacing and configuration. The rebar is tied together using ties or wire mesh to ensure stability and structural integrity.

Placing the formwork

Once the steel mesh is erected, the next step in the Mivan shuttering construction process is to place the formwork. The formwork consists of shuttering plates or forms that are specifically designed and pre-integrated with openings for doors and windows.

The placement of the formwork is carried out by skilled laborers who position the forms according to the layout and design of the structure. The forms are placed in their designated positions, ensuring proper alignment and spacing.

To join the forms together, a pin and wedge system is used. This system involves inserting pins into pre-drilled holes in the formwork and securing them with wedges. The pins and wedges effectively hold the forms in place, maintaining their shape and stability during the concrete pouring process.

One of the advantages of Mivan formwork is its ease of handling, which allows for speedy construction. The lightweight aluminum forms are easy to maneuver and assemble, reducing the time and effort required. This facilitates faster construction progress and increased efficiency on the construction site.

Pouring Concrete into Structural Components

Once the formwork is in place, the next step in the Mivan shuttering construction process is casting the structural elements with concrete. This involves pouring concrete into the formwork to create a strong and rigid structure. The process of pouring and placing concrete in Mivan shuttering is similar to the traditional formwork method.

The concrete is carefully mixed to achieve the desired consistency and strength. It is then poured into the formwork, ensuring that it fills all the designated areas and completely surrounds the reinforcing steel. The concrete is compacted using vibrators to remove any air voids and ensure proper consolidation.

During the casting process, it is essential to monitor the concrete placement and ensure a uniform distribution throughout the formwork. This helps in achieving a consistent and reliable structure.

Once the concrete is poured, it is allowed to cure and gain strength over time. The curing period may vary depending on the type of concrete used and the project requirements. It is important to follow proper curing practices to ensure the durability and longevity of the structure.

Deshuttering the formwork

Once the concrete has gained sufficient strength and rigidity, the next step in the Mivan shuttering construction process is the deshuttering of the formwork. Deshuttering refers to the removal of the formwork from the concrete structure.

One of the advantages of using Mivan formwork is its ease of handling, which also applies to the deshuttering process. Due to the efficient design and lightweight nature of the aluminum forms, the deshuttering can be done without much complexity. The formwork can be easily dismantled and removed from the structure.

After the formwork is removed, the concrete structure is left with a superior quality finish. The smooth surfaces of the Mivan formwork result in a clean and well-finished concrete surface. This eliminates the need for any additional plastering or finishing work on the structure.

The absence of plastering not only saves time and effort but also contributes to the overall aesthetic appeal of the structure. The natural texture and appearance of the concrete can be showcased, providing a modern and contemporary look.

Advantages of Mivan Shuttering

  • Mivan formwork is constructed of aluminum alloy. Thus, it has great durability.
  • Mivan formwork can be erected quickly, allowing for faster construction and deshuttering.
  • Unskilled laborers can also perform the erection.
  • The structure constructed using Mivan formwork has strong seismic resistance.
  • It can be used at least 250 times.
  • It is not necessary to use bricks or masonry blocks because all the structural components are made of concrete. Therefore, compared to masonry components, concrete has a significantly higher strength.
  • The structural components are uniform.
  • The finished concrete produced is of higher quality. As a result, it reduces the need to plaster the structure.

Disadvantage of Mivan Shuttering

  • Mivan shuttering is customised to meet the specific needs of the structure; therefore, there are fewer opportunities for structural component alteration.
  • Mivan formwork has an initial cost that is higher. Thus, it is inappropriate for small projects.
  • Skilled laborers are needed to make sure that concrete is properly poured, alignment is completed on schedule, etc.
  • Ensure correct construction joint connections to prevent slurry leaks.
  • Cracks are prone to form because of shrinkage in box-type construction. However, this issue can be avoided by utilizing fly ash to reduce heat hydration or by installing control strips on the structure.
  • Due to the small size of the components, the completed structure could have visible finishing lines on the concrete surface.
  • The shear walls contribute to a relatively higher heat of hydration.
