What are the advantages and disadvantages of using Aluminium?

Aluminium

• Advantages: The most abundant metal in the Earth’s crust, Aluminium is relatively soft, durable, lightweight, ductile and malleable metal.
• Disadvantages: It’s not particularly strong and is expensive compared to steel of the same strength.

Why is Aluminium formwork used?

Aluminium Formwork System is a construction system for forming cast in place concrete structure of a building. It is also a system for scheduling and controlling the work of other construction trades such as steel reinforcement, concrete placement and mechanical and electrical conduits.

What are the disadvantages of formwork?

Disadvantages of timber formwork

• Can’t be used for long.
• If the timber is dry, it will absorb moisture from wet concrete which could weaken the resultant concrete member.
• Timber with high moisture content (more than 20 \% moisture content), wet concrete will shrink & cup leading to open joints & leakage of grout.

What are some disadvantages of aluminum?

Disadvantages

• Can create a mess! Aluminium fabrication isn’t for the faint-hearted, as using low melting heat and melting process means that aluminium does tend to create a mess as it can build up in the wheels during the grinding process.
• Sensitive to heat.
• The conductor of heat and electricity.

What are disadvantages of aluminum?

What is the grade of aluminium formwork?

6061 T6 grade aluminium is best suited for formwork construction because of the below-mentioned properties: Machinability: 6061 exhibits good machinability properties in the T6 temper., making it easier to work upon.

What are the advantages of steel formwork?

Steel forms are durable and stronger. Provides uniform and smooth surface finish to the structure. Great reusability. Easy to fix the formwork and also easy to dismantle.

What are the advantages and disadvantages of timber formwork?

Advantages

• Timber can be cut into any required size easily.
• Timber is light in weight and it can be handled easily.
• Timber has good thermal resistance which prevents the damage of concrete in colder regions.
• It is easy to understand the construction method of timber formwork hence, skilled workers are not necessary.

What are the disadvantages of timber?

Timber shrinks, swells, twists, cracks and bends over time and different climatic conditions. Most timbers are prone to pest, rot, mold and fungi attacks, some are far better than others but they both require a minimum of LOSP or ACQ treatments for outdoor structures.
