Abstract

This article studies whether newly developed synthetic macrofiber can enhance the strength properties of plain and fiber-reinforced concrete slabs-on-ground. The structural behavior of fiber-reinforced concrete slabs under interior and edge loading conditions were tested. The results of the load testing showed that the failure behavior of plain concrete slabs was significantly modified with the addition of synthetic fibers, but that the synthetic fibers did not change the tensile cracking load of the plain concrete slab. Strain gauges embedded in the concrete slabs indicated the fibers distributed the load-carrying capacity throughout the slab volume, increasing the concrete slab flexural and ultimate capacities.
