Slab-on-Ground Case Studies about Synthetic Fiber-Reinforced Concrete

Abstract

This paper describes how synthetic fibers provide a type of three-dimensional reinforcement for concrete with several benefits, especially in slab-on-ground applications. Any design process, and specifically design of synthetic fiber-reinforced concrete, involves making some decisions based on performance-quality, schedule, and cost assumptions. Further, most designs can be analyzed for material substitution of conventional steel reinforcement bending moments with synthetic fiber reinforced concrete bending moments. The design process for slabs-on-ground and substitution with synthetic fiber-reinforced concrete is analyzed for consistency and compared with other design procedures, based on what is known and not known about the synthetic fiber-reinforced concrete material behavior from testing and field performance. Case histories are presented about how these dosages of synthetic fiber-reinforced concrete were used and constructed, and regarding their performance including what was and was not expected.
