Abstract:

Concrete columns are traditionally produced by placing concrete into a mold or form. Assembling and then removing the formwork takes time and labor; and eventual replacement of the formwork leads to increased material use and transport costs. A new alternative, a permanent three-dimensionally (3-D) printed concrete form in which a core is cast with self-consolidating concrete, was investigated in this project.

Abstract:

For all concrete structures, cost effectiveness is heavily influenced by the timing of formwork cycling. For post-tensioned structures, review and approval of elongation records is a critical step within each formwork cycle. This article explores the timeliness of reviews, purpose of elongations and tolerances, evaluation of stressing records, and reasonable expectations for all stakeholders.
