Key aspects of concrete forming:

• Purpose: To hold the wet concrete in place and give it the required shape until it cures and hardens. 
• Materials: Common materials include wood, steel, and plastic. 
• Types: Formwork can be temporary (removed after the concrete sets) or permanent. 
• Importance: Formwork is essential for shaping and supporting concrete structures, ensuring their structural integrity and desired finish. 
• Process: Formwork is constructed, concrete is poured into it, and then the concrete is allowed to cure before the forms are removed (in the case of temporary formwork). 
• What type of concrete forms are left in place permanently? Insulating Concrete Forms Insulating Concrete Forms (ICFs) are concrete wall forming systems that are not removed after the concrete has hardened, but stay in place permanently as part of the structure. The forms are generally made from high density styrofoam or other lightweight materials.

STRIPPING - The process of removing Formwork after concrete has set, typically occurs 24-48 hours after pouring for walls and columns, and 3-4 days for slabs, with props remaining in place. The exact timing depends on factors like concrete type, load-bearing requirements, and environmental conditions.
