An alternative is to cast the concrete around tendons that are greased or encased in a plastic sleeve. When the concrete has sufficient strength the tendons are tensioned by means of portable jacks. WebA post-tension slab generally refers to a section of cured concrete, which has tensile forces introduced into the slab after the concrete has been set. These internal forces are provided by tensioning the high-strength steel that occurs before or after the concrete is positioned. chic 1970\\u0027s vintage fashion shop
