Method & Evidence

AimTo investigate the mechanical performance and durability of cement-based matrices reinforced with recycled aramid textile nonwoven fabric, and compare it to other fabric-reinforced cementitious matrices (FRCMs).
MethodExperimental characterization
ProcedureLaminated fabric-reinforced cementitious matrices (FRCMs) were created using 4 and 6 layers of recycled aramid textile nonwoven fabric from end-of-life fire-protecting t-shirts. The composite panels were subjected to forced aging (dry-wet and freeze-thaw cycles). Mechanical properties, including direct and flexural tensile strength, toughness index, and modulus of rupture, were measured after 28 days of curing.
ContextConstruction materials, sustainable building components, waste recycling

Variables
