When creating post-tensioning wedges, several critical factors must be thoroughly evaluated. The wedge's geometry significantly affects the load transfer process, and its substance directly impacts strength and durability. The chosen wedge style must match the specific application requirements, including the tendon diameter, concrete strength, and
Comparing Internal and External Post-Tensioning Techniques
Post-tensioning is a widely employed technique in concrete construction to enhance the strength and durability of structures. There are two primary methods of post-tensioning: internal and external. Internal post-tensioning involves embedding steel strands or cables within the concrete itself during the casting process. These strands are then tensi
