Study on the Effects of Printing Process and Reinforcement Materials on the Performance of 3D-Printed Glass Bead Insulation Mortar

In the polypropylene fiber dosage of more than 0.6%, the compressive strength of mortar with the increase in fiber dosage is a decreasing trend, which may be due to the fiber dosage being too much, the mortar mixing not being uniform, the fiber being easy to agglomerate inside the mortar, and the formation of weak points, leading to the compressive strength of the mortar being reduced.
