What is Mivan Technology? Advantage & Disadvantage of Mivan Shuttering.

Mivan Technology

The monolithic construction has been rapidly booming around the globe because of many advantages. Mivan technology is one of those methods which helps you have desired outcomes. This technology is not very popular in India but is very popular in Gulf countries, Europe, and some parts of Asia.

What is Mivan Technology?

Mivan technology uses an aluminium formwork structure which helps us constructing various structural elements simultaneously. Mivan Technology is named after a European construction firm, Mivan Company Ltd. which came up with this method. Formworks of mivan consists of strong and robust aluminium components that are durable and easy to install, and is used for large sized construction within less time.

Components of Mivan Formwork:

Disadvantages of MIVAN:

  •  Alignment of formworks need skilled laborers.
  • Initial setup is time consuming.
  • It is expensive.
  • It is used for typical floors only.
  • Construction joints should be set meticulously.
  • Leakage issue like seepage, leakages during monsoon.

 

Construction steps using Mivan Formwork:

 

  1. A prefabricated steel mesh is prepared in factory which is brought on the site and is installed for reinforcing whole structure which acts as a support to the concrete until it gains 50% of the design strength.
  2. Along with the wall steel mesh, wall panels and floor slabs are erected.
  3. Plumb, level and alignment are checked.
  4. Openings for windows, doors, ducts etc are left.
  5. All the formwork is then connected using pins and wedge system, which can be dismantled soon after pouring concrete.
  6. Concrete is poured after successfully installing the formwork.
  7. Pins, wedges and props are taken care of during concreting.
  8. Generally, after 12 hours of concreting, vertical elements are struck down.
  9. Removed formwork is scrapped and cleaned properly.
