Sprayed fire resistant materials (SFRMs) are widely used as passive fire protection for steel construction. As a type of concrete, they are inherently brittle. SFRMs can therefore delaminate from steel due to service or impact loads, creating gaps through which heat can penetrate, rendering the SFRM useless. A new class of SFRMs was proposed in this study that uses nylon fibers to create a fiber reinforced concrete. The SFRMs synthesized over the course of the study had first crack strengths 5-15 times greater than typical SFRMs and tensile strain capacities 30-40 times greater than typical SFRMs. The strain capacities could be improved upon in future testing by increasing the volume of fibers in the concrete, which would foster a strain-hardening behavior in the
