Abstract:
Contraction joints are not commonly used in residential post-tensioned (PT) slabs-on-ground. However, they are permitted by the Post-Tensioning Institute as means to minimize random cracking and improve appearance of a slab. The article discusses importance of contraction joints in PT slabs, determination of a joint layout, and available installation methods.
