CI4707ConcreteQA
This month’s Q&A focuses on issues related to meeting in-place concrete strength requirements for removing forms for reinforced concrete slabs. It explains how the contractor might accelerate the construction schedule by implementing concrete mixtures with compressive strengths exceeding those specified for the project.

An improvement project on a 23-mile (37 km) section of Interstate 17 (I-17) in Arizona, USA, includes widening of 15 miles (24 km) of roadways, replacing two bridges, widening of 10 additional bridges, and constructing 8 miles (13 km) of flex lanes. PERI USA provided customized and fully rentable formwork/falsework for concrete construction on this project.

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.

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.
