“…This can be attributed to the inability of the synthetic fibers to be dispersed homogenously in the SCC mixture and to agglomerate due to the low shearing effect of the mixer used in the preparation of the mixtures. In some studies [35][36][37][38][39], it was also determined that the use of PP and PVA fibers into concrete adversely affect the fresh properties of SCC mixtures. Thus, the decrease in the filling rate of the mixtures affected the fc of concrete negatively.…”

This study presents the experimental results about the effects of Polyvinyl-alcohol (PVA) and Polypropylene (PP) fibers on the fresh and mechanical properties including compressive, splitting tensile strength, modulus of rupture (MOR) as well as toughness of the hybrid fiber reinforced self-compacting concrete (SCC). PVA and PP fibers were added into SCC mixtures having only macro steel fiber and also having binary hybridization of both macro and micro steel fiber. The results showed that the use of micro steel fiber replaced by macro steel fiber improved the workability, compressive and splitting tensile strength, MOR and toughness and also caused reduction in the weight loss percentage compared to the use of only macro steel fiber. Moreover, it was emphasized that PVA or PP enhanced the residual flexural performance of SCC, generally, while it negatively influenced the workability and the residual strengths according to the use of single steel fiber and binary steel fiber hybridization. Compared to the effect of synthetic fibers, PP had slightly more positive effect in the view of workability while PVA enhanced the residual mechanical properties more.

Cement-based materials are the most widely utilized construction materials in the world owing to their high compressive strength, however, need reinforcement to withstand direct or indirect tensile forces. In this study, the potential use of 3D-printed polymers as an alternative reinforcement in cement-based composites was evaluated. Polyethylene terephthalate glycol (PETG), Polyamide (PA), and Acrylonitrile butadiene styrene (ABS) based triangular and honeycomb-patterned 3D-printed reinforcements were incorporated into cement-based composites and their mechanical performances were compared under three-point flexural tests by considering both polymer and pattern type. Both triangular and honeycomb patterns were enhanced the flexural behavior. By considering all filaments, the honeycomb pattern was found more effective than the triangular pattern for increasing flexural strength, deflection capacity, and toughness up to 46.80%, 251.85%, and 77.66%, respectively. In the case of filament type, 3D-printed PA-type filament in a honeycomb pattern remained flexural strength, enhanced deflection capacity, and increased flexural toughness with pseudo-deflection hardening behavior. 3D-printed honeycomb patterned reinforcements produced by PA has the opportunity to be used in the manufacture of cement-based composites.
