Abstract:

This month’s Q&A discusses the reinforcement stiffness ratio ρne that can be used for comparing the performance of various reinforcement types in slabs-on-ground and the design approach for glass fiber-reinforced polymer reinforcement in ACI/NEx MNL-6(23) based on percent reduction in unrestrained shrinkage strain from the enhanced aggregate interlock design of ACI PRC-360-10.

Abstract:

This article introduces the latest fiber-reinforced polymer panel system developed by the author—SPiRe®+. These panels can serve as formwork, corrosion resistant reinforcement, and waterproofing. With their flat and smooth exterior face and protruding T-profiles on the interior face, the panels act as reinforcing elements for strengthening beams, slabs, and walls.
