Abstract |
In this study, the 3D printing quality of fiber-reinforced mortar incorporating a recycled cactus powder admixture wasevaluated. Rheological properties, visual characteristics (printing continuity and surface pore distribution), and 3D printing accuracy(dimensional error rate and layer thickness accuracy) were experimentally investigated. Experimental variables included fibervolume fraction and the amounts of superplasticizer (SP), methyl cellulose, and recycled cactus powder admixture (CS). The CS usedin this study was obtained by crushing discarded cactus stems into a dry powder. Results indicated that mortar fluidity increased asthe amount of CS increased. Furthermore, adjusting the amounts of CS and SP allows for control over fluidity changes associatedwith varying fiber volume fractions, and enables improvement of the printed product’s surface quality.
