A Guide to Fabric-Formed Concrete

Editor's Note: With this Guide to Fabric-Formed Concrete it is hoped that existing and new techniques that may come along can be documented here for the benefit of others who wish to use this truly unique method of forming concrete for their projects. The Table of Contents shown below contain topics similar to ACI's SP-4 Formwork for Concrete as it is assumed there will be many similar considerations for Fabric-Formed Concrete as well. Topics that may not be applicable can be marked with a question mark, “?”. Pages have been created for each <fc #0000FF>CHAPTER</fc> of this document and may accessed by clicking on the hyper-link, <fc #0000FF>blue text</fc>. Headlines have also been created for each chapter topic. Within these headline topics content may be added by selecting the “<fc #0000FF>edit</fc>” link on the right-hand margin. Or, by selecting the “edit tab” at the top of the page, the entire page may be worked on. Where appropriate hyper-links may be added to connect topics on different pages (Chapters). Just use the Internal Link button in the Editorial Toolbar when in edit mode. This is an evolving work where topics and pages can be added or deleted as required.
