Experimental evaluation of mechanical strength of silica fume-cemented sand reinforced with 3D-printed fibers

Popis výsledku v původním jazyce

3D printing has revolutionized building design and construction with rapid, cost-effective production of complex designs approaches. Cementitious materials have low mechanical properties and ductility, and may not be an ideal choice for a sustainable design. One of the useful methods to improve the behavior of cementitious materials is using fiber reinforcement. The current study aims to investigate the potential use of 3D-printed fibers for reinforcing silica fume-cemented sand. For this purpose, the mechanical and microstructural properties as well as the fracture mechanism of silica fume-cemented sand reinforced with 3D-printed fibers made from Polylactic Acid plus (PLA+) materials have been investigated. Four different fiber geometries-straight, enlarged-end, intended, and hooked-end-as well as four different percentages of 3D-printed fibers-0, 0.3, 0.6, and 1 % by weight of dry sand-were taken into consideration. All types of 3D-printed fibers were able to change the brittle behavior of silica fume-cemented sand to a more ductile one. The findings of microstructural analyses were also in line with the outcomes of the mechanical experiments. This study&apos;s experimental validation showed that the mechanical characteristics of silica fume-cemented sand reinforced with 3D-printed fibers were improved.
