How to Calculate Concrete Volume For Slump Test

HELLO FRIENDS
I am uploading my documents for you only on your request, So that you can download it from here. But one thing keep in mind that this is only the hand made notes. If you want detailed knowledge then watch my video on you tube. I am telling this because many important points i cover during making of video, so if you want to know in detail then watch my video.

ALUMINIUM FORMWORK : DISMANTLING PROCESS

Sequence No. 1

After 24 hours, remove the internal wall panels by knocking out the wedges and pins. The wall panels are to be moved to upper floor through the slab opening as shown. The transferring of panels should be done in a systematically and orderly manner to ensure that the next cycle or level is not affected. Since all the panels are numbered with different colour identification scheme, these transfer process can be determined and planned in advance according to section of the building such as Room 1, Room 2, Bathroom are etc.



Sequence No. 2

After removing the external wall forms (the starter block [kicker] should remain undisturbed), the dismantled wall forms are moved to upper floor. Access Scaffolding is use for transferring of external wall panels from the ground floor level. For level 1 and above, an external working platform is fixed to the external wall. The external wall forms from level 1 onward shall be supported by the kickers. (These steps are to be repeated from one floor to another floor)



Sequence No. 3

After removing the wall panels, proceed to the slab panels after 36 hours by removing the long pins and wedges on the joint bars the end and middle beam section.



Sequence No. 4

Upon removing the Alu spans Mid Beams and Alu span cantilevers End Beams, the prop shall remained undisturbed during this process to support the concrete slab.



Sequence No. 5

Proceed to strip the slab panels and transfer to the next level according to the designated area and installation sequence.



Sequence No. 6

Strip the slab corner



Sequence No. 7

Pull out wall flat tie using wall tie puller and remove the wall tie sleeve using nose player.


Sequence No. 8

When the cube tests show that the slab concrete is sufficiently strong, the group together with the prop heads are removed and transferred to the next level.








ALUMINIUM FORMWORK : ASSEMBLY PROCESS

Sequence No. 1

Form Release agent (Solvent based) to be applied on the surface of all the panels before the assembly process.



Sequence No. 2

Outer Corner is fixed to External Wall Corner panel by round pin and wedge.



Sequence No. 3

Inner Corner is fixed to the Internal Wall panels by round pin & wedge. The Internal and External Wall Panels are hold by Flat Tie with Tie Bar Shield in between the panels.



Sequence No. 4

Repeat Sequence No. 3 to complete the assembly of both the Internal and External Wall Panels.



Sequence No. 5

Install Slab Corner on the top portion of the Wall Panels with round pin & Wedge.



Sequence No. 6

Alu spans mid beams / end beams and prop head are combined by beam splice bar with long pin and wedge at the bottom section.



Sequence No. 7

Start the assembly of the Slab Panels from the slab corner Internal. Subsequently, fill out the whole slab area by pinning the slab panels together with the Alu spans (Comprises of Alu spans and cantilevers) Mid Beams / End Beams.



Sequence No. 8

Additional Wall Panels (or Kickers) are fixed to the external Wall Panels to raise to the appropriate height to contain the slab concrete when it is poured.



Sequence No. 9

Upon completion of the installation and fixing of the wall and slab panels, a numbering sequence will be made for each of these panels with colour identification scheme to differentiate each of the unit area such as bedrooms, living room, bathroom etc. This numbering and colour identification scheme will ensure that each panels can be determined as to their exact location once they are transferred to the next level for installation.



Sequence No. 10

Always ensure that wall ties, pins and wedges are properly installed and secured before pouring concrete into the forms. Ensure that concrete pouring is distribute evenly throughout the wall panels section before commencing to cast the slabs level area.
