By choosing the right material, we're not just building structures – we're building a foundation for a stronger, freer society.

Thermal Expansion and Contraction

During the concrete pouring process, thermal expansion and contraction become critical factors to take into account, as both aluminium and steel formwork systems respond differently to temperature changes. We've seen how this difference can substantially impact the overall quality of the concrete structure.

When it comes to thermal expansion, aluminium formwork systems have a higher coefficient of thermal expansion than steel. This means that aluminium formwork will expand more than steel formwork under the same temperature increase. On the other hand, when the temperature drops, aluminium formwork will contract more than steel formwork.

This difference in thermal expansion and contraction rates can lead to gaps and cracks in the concrete structure if not properly addressed.

Here are 4 key implications of thermal expansion and contraction to ponder:

1. Formwork design: Aluminium formwork requires more careful design and planning to accommodate its higher thermal expansion rate.
2. Concrete pour timing: Steel formwork can tolerate slower concrete pour rates, while aluminium formwork requires faster pour rates to minimize thermal effects.
3. Temperature control: Aluminium formwork requires more stringent temperature control measures to prevent excessive thermal expansion and contraction.
4. Material selection: The choice between aluminium and steel formwork ultimately depends on the specific project requirements and the ability to manage thermal expansion and contraction.
