In concrete construction, formwork is our temporary mold, shaping structures until the concrete gains enough strength to support itself. But do you know that removing formwork too early can compromise the structural integrity, while keeping it for too long can delay projects unnecessarily?

Striking time is the period we allow concrete to achieve sufficient strength before removing the formwork. Factors influencing this include:

Concrete mix and grade

Ambient temperature and humidity

Structural member type (slabs, beams, columns)

Why it matters:

Premature removal can lead to cracks, deflection, or even failure.

Proper timing ensures design strength, durability, and long-term performance.

Optimized striking time balances safety and project efficiency, avoiding delays or extra costs.

As engineers, understanding and respecting striking time is key to delivering safe, durable, and cost-effective structures.

Remember: Concrete strength grows over time patience is part of quality.
