MIVAN TECHNOLOGY IN CONSTRUCTION PDF
4 Mar Mivan’ is basically an aluminium formwork construction technology developed by Mivan Company from Malaysia, hence the name Mivan. 18 Sep Mivan tech. 1. Mivan Technology TEJAS ; 2. Introduction • It is the information about AdvanceTechnologies In Building Construction. 21 Jun Achieving the “3-S” system in the MIVAN formwork is quite easy. MIVAN formwork has got the unsurpassed speed of construction due to saving.

Oct-Decpp But again, such construction methods mean huge investments and are not feasible for small construction projects. The strength of raw aluminium is very less but when alloyed with other materials prove to be strong enough to use as a formwork. Staircase flights, facade panels, chajjas and jails etc. There are basic three methods recommended when transporting to the next floor: Also in cases where the cost supersedes the time, in terms of priority this technology tends to become redundant.
Pins, wedges or wall ties missing could lead to a movement of the formwork and possibility of the formwork being damaged. It has good thermal insulation which makes it useful to be used in colder Regions.
CIVIL ENGINEERING SEMINAR TOPICS: MIVAN TECHNOLOGY
The most important factor in terms of cost, quality and speed in a high-rise building construction project is the type of the formwork used in the project. Overspill of concrete at window opening etc. 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 system involves structural elements such as pre-cast hollow column shells pre-cast concrete beams, light weighed reinforced cellular autoclaved concrete slabs for floor and roofs constituting the basic structural formwork.
Merits And Demerits Of Mivan Technology
Formwork is defined as temporary structure whose purpose is to provide support and containment for fresh concrete until it can support itself. Mivan is an Aluminium formwork technology where the whole structure is of RCC Reinforced Cement concrete and brick walls are not used.
This facilitates fast construction, say two flats per day. This pressure depends upon the quantity of water in the concrete, rate of pouring and the temperature. Thank you for your enquiry. Pre-cast includes the wall-panel units and slab units directly added to building structure. Further, such constructions are prone to poor quality control even in case of contractors with substantial resources and experience.
At least two operatives should be on standby during concreting for checking pins, wedges and wall ties as the pour is in progress. Posted by Visit n’ Tech at 4: 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. Some experts feel that housing alternatives with low maintenance requirements may be preferred even if the initial cost is high.
Higher carpet area- is increased due to shear walls the walls are thin thus increasing area. This produces a lightweight panel with an excellent stiffness to weight ratio, yielding minimal deflection under concrete loading. The concrete is produced in RMC batching plants under strict quality control and convey it to site with transit mixers.
The speed of construction by this system will surpass speed of most of the other construction method.
Irrespective of so many attractive advantages, the demerits of this formwork cannot be ignored. Aluminium formwork system is construction cobstruction for forming cast in place concrete structure of building. Prem Mohan July 12, at 6: It is Suitable for circular or curved shaped structures such as tanks, columns, chimneys etc.
This in turn resulted in these properties being unattainable to many. It allows the contractor to pour structural and finished concrete simultaneously. Anil June 29, at 8: However, because of their lower density, aluminum forms are lighter than steel forms, and this is their primary advantage when compared to steel.
It takes about hrs. Further, the system is quite flexible and can be easily adapted for any variations in the layout.
Merits And Demerits Of Mivan Technology
Rapid construction of multiple units of a repetitive type can be achieved with a sort of assembly line production by deployment of a few semi-skilled labors. In Construction, the formwork has to bear, besides its own weightthe weight of wet concretethe live load due to labor, and the mivn due to pouring concrete and workmen on it.
However, due to the depleting forest reserves and increasing cost of timber the use mivn alternate materials such as plywood and steel has become prominent. It should have sufficient strength characteristics. The system of aluminum forms MIVAN has been used widely in the construction of residential units and mass housing projects.
This is not the case with moladi as the components are small and movan assembled on site or field with ease and can also be removed and replaced if required Plastic is moulded at temperatures above deg Celsius, Cement kicking off will therefore not have any negative effect on the plastic formwork.
The post — concreting activities includes: In fact, time consuming repairs and modifications due to poor ij work generally delay the job and cause additional financial impact on the project.
