The cost of formwork accounts for a little portion of the construction cost. While the formwork is the most space-saving and cost-effective turnover material. It is really a good choice to use formwork in construction projects.

Aluminum formwork is a new kind of formwork. It has become the most popular formwork system in China due to its durability and easy installment. The aluminum formwork is on the road to replace the traditional formwork, square wood, and steel pipe. It is equivalent to the formwork system plus the supporting system.

Aluminum formwork has fast development. But nowadays, there are only a few projects using aluminum formwork in the domestic. And the people in the engineering construction industry only have a basic understanding of it, which shows that aluminum formwork is still not widely used in China though it has many outstanding features.

The following are some of the advantages and disadvantages of aluminum formwork.

Advantages:

1. Produced according to the industrial standard, stable quality.

2. Precise determination, high bearing capacity, relatively stable concrete forming.

3. Skillful workers have high construction efficiency.

4. It can be equipped with a quick-release system, less on-site garbage.

5. High recycling use rate, it can be recycled and refurbished.

Disadvantages:

1. High cost and the one-time investment is large. Even if it is rented, the cost is high.

2. After the deformation, it is difficult to repair, generally, a small deformation will lead to a large piece affected.

3. Workers must have corresponding construction techniques, otherwise, the efficiency is low and the effect is poor.

4. Aluminum alloy surface and concrete are prone to oxidative corrosion, resulting in bubbles affecting concrete molding.

5. The energy consumption of electrolytic aluminum production is large, and an oily release agent is required for use.
