- 2. MIVAN (SHUTTERING) FORMWORK Mivan shuttering is a fast-paced construction technique that offers strength and durability to a building through the use of aluminum formwork. With a growing focus on affordable housing and “Housing for All“, real estate stakeholders are increasingly emphasizing the use of new and innovative construction techniques. One of these technologies is the Mivan shuttering, which is being promoted for its ability to assist mass construction activities. 1. 2. 3. 4.
- 3. Mivan Technology, or the aluminum formwork system, was developed by a European company. In technical terms, a large number of houses can be built at a much faster speed using Mivan shuttering, as this formwork construction system runs the structural 1. 2. 3. 4. MIVAN (SHUTTERING) FORMWORK

- 5. FEATURES OF MIVAN FORMWORK The main features of the Mivan formwork are presented below Load Capacity The load capacity of the Mivan formwork is 7-8 tonnes per square meter. The Mivan formwork is light and weighs about 18 to 20 kg per square meter. Hit Time The impressive vertical formwork time (wall) is 12 hours after pouring or when the concrete strength reaches 2N / mm2 and the horizontal formwork (deck) is 36 hours after pouring or when the concrete strength reaches 10N / mm2. Durability As the Mivan formwork panels are made of structural quality aluminum alloy, they are very durable and resistant. A single component can be repeated about 200 times. Cycle time High construction speed can be achieved by this system, which means faster completion of the project. Approximately, the time required to lay
- 6. PROCEDURE OF MIVAN FORMWORK INSTALLATION 1. Placing Aluminum Formwork Mivan formwork is mainly used in places where all structures are made of concrete. The entire formwork is cleaned and coated with approved design agents. The wall reinforcing steel is placed with the slab. Along with the wall reinforcing steel, prefabricated wall panels the size of rooms and slab panels are assembled. Plumb, level, and dimensions are checked. Aluminum alloy slabs are precisely made to the required sizes. Spaces for windows, ducts, doors and other resources, such as stairs, facade panels, and flares are also integrated into these structures. The forms are then joined using the pin and wedge system, which can be dismantled quickly after the concrete structure is built.
- 7. PROCEDURE OF MIVAN FORMWORK INSTALLATION 2. Pouring concrete After molding the forms, high-quality concrete is poured. This concrete takes the form and shape of the mold. At least two agents must be on standby during pouring to check pins, wedges, and clamps as the leak is in progress. Special attention to be paid when pouring concrete to dislodge pins/wedges, slipping of props or overflowing concrete in the openings. 3. Formwork Strike Normally, all forms can be achieved after 12 hours of pouring. First, the wall mold is dropped, followed by the deck mold. The removed formwork is cleaned with scrapers and wire brushes as soon as they are Once cleaned, it is transported and stacked properly for the next use.
- 8. Advantages •Speed – reduces the total rotation time by almost half when compared to conventional construction techniques. •Requires less work – With a defined procedure and checklists to follow, this technology minimizes the need for skilled labor and also eliminates activities such as masonry and rendering activities that require a lot of work. •Seismic and Durable Resistance – Buildings are more resistant to seismic and more •Less maintenance – Mainly without construction joints and with free-flowing concrete used, this technology reduces the chances of infiltration, which results in negligible •Smooth Finish – The construction of the Mivan ensures uniformity, therefore, all walls and slabs have a smooth finish, which means that no additional plastering is required. •Larger carpet area – offers the possibility of removing more carpet area compared to traditional construction techniques. •Earthquake resistant – more earthquake resistant and safer in the event of a strong This is because the structures built using the Mivan are monolithic concrete structures that act as a single strong unit.
- 9. Disadvantages Expensive – aluminum shapes are very expensive than conventional shapes. Visible finishing lines – Due to the small size components, the finished structure can have several finishing lines visible on the concrete surfaces. Less scope for changes – Changes or modifications are not possible as all members are posted to the RCC. Requires uniform planning – This technology is comparatively expensive, so uniform economic planning and upgrades are required. It may have contraction cracks – Shrinkage can result in cracks in the walls and slabs. This can be avoided by reducing heat hydration using fly ash or control strips on the structure.
