- 2. MIVAN FORMWORK FORMWORK • Formworkis the temporary moulds or shutters in which concrete is placed, so that it will have desired shape or outline when hardened. This temporary casing is known as Formwork orShuttering.
- 3. WHAT IS MIVAN FORMWORK Mivan is the Brand name from far East,Malaysia. It is Aluminium Alloy Formwork. The system of Aluminium forms (MIVAN) has been used widely in the construction of residential units and mass housing projects. It is fast, simple, adaptable and cost effective. It produces total quality work which requires minimum maintenance and when durability is the prime consideration. Aluminum Formwork system is a comparatively a new technology in India.
- 4. HISTORY & BACKGROUND Mivanis basically an aluminum formwork system developed by one of the construction company from Europe. In 1990, the Mivan Company Ltd from Malaysia started the manufacturing of such formwork systems. Now a days more than 30,000 sq. m of formwork used in the world are under their operation. In Mumbai, India there are number of buildings constructed with the help of the above system which has been proved to be very economical and satisfactory for Indian Construction Environment. The technology has been used extensively in other countries such as Europe, Gulf Countries, Asia and all other parts of the world. MIVAN technology is suitable for constructing large number of houses within short time using room size forms to construct walls and slabs in one continuous pour on concrete. All the activities are planned in assembly line manner and hence result into more accurate, well – controlled and high quality production at optimum cost and in shortest possible time.

- 13. ADVANTAGES OF MIVAN FORMWORK •More seismic resistance:-Thebox type construction providesmore seismic resistance to thestructure. • Increased durability: -Thedurability of acomplete concrete structure ismore than conventional brick bat masonry. • Lessernumber of joints thereby reducing the leakages and enhancing the durability. • Higher carpet area- Due to shearwalls the walls arethin thus increasing area. • Integral and smooth finishing of wall and slab-Smooth finish of aluminum canbe seen vividly onwalls. • Negligible maintenance –Strongbuilt upof concrete needsno maintenance. • Fastercompletion –Unsurpassedconstruction speedcanbe achieved dueto light weight of forms. • Lessermanuallabour- Lesslabour isrequired for carrying formworks. • Simplified foundation design dueto consistent load distribution.
- 14. LIMITATIONS • Because ofsmall sizes finishing lines are seen on the concrete surfaces. • Concealed services become difficult due to small thickness of components. • It requires uniform planning as well as uniform elevations to be cost effective. • Modifications are not possible as all members are caste in RCC. • Large volume of work is necessary to be cost effective i.e. at least 200 repetitions of the forms should be possible at work. • The formwork requires number of spacer, wall ties etc. which are placed @ 2 feet c/c; these create problems such as seepage, leakages during monsoon. • Due to box-type construction shrinkage cracks are likely to appear. • Heat of Hydration is high due to shear walls.
