Keywords Method development to evaluate steel fiber performance in concrete with expansive additives under restrained conditions
Abstract Novel steel molds in form of a rigid cubical shell were developed in order to investigate single steel fiber pull-out resistance in concrete with expansive additive under restrained hardening conditions. The developed steel molds simulate internal (from steel fibers) and external (from friction against sub-base) restraints that hinder expansion of the concrete in a flooring slab structure installed on ground. Samples with a single hooked-end steel fiber, with and without expansive additive were manufactured and tested in the developed mold geometry. The results show that restrained concrete expansion positively affects single fiber pull-out behavior, i.e. fiber delamination resistance is increased by 29.7 % and pull-out peak load by 10.8 %.
