Method & Evidence

AimTo investigate the mechanical behavior, cracking mechanisms, and autogenous healing capabilities of cementitious composites reinforced with varying layers of curaú fabric.
MethodExperimental testing and analysis
ProcedureComposites with one, three, and five layers of curaú fabric were fabricated. Mechanical properties were assessed using direct tensile and four-point bending tests. Crack formation and propagation were analyzed using image analysis and Digital Image Correlation (DIC). The influence of flexural cracking on the neutral axis was studied with strain gauges. Autogenous healing was evaluated through cyclic and constant load bending tests on a three-layered composite.
