Formwork is essential for concrete construction, creating the temporary molds that shape wet concrete. While 3/4" plywood is standard, materials like steel and specialized coatings enhance reusability and durability. Key considerations include the formwork's strength to withstand immense concrete pressure and its constructability for easy assembly and removal. Modern advancements offer innovative solutions, such as insulated concrete forms (ICFs) that provide both structure and insulation, and specialized techniques like slip forming and flying forms that optimize efficiency for repetitive structures.
