Description
Xingyu Qu and co-authors try to keep 3D-printed cement from slumping before it sets. Their base is white calcium sulfoaluminate cement, prized for bright architectural finishes. Into it they stirred two marine waste powders in this 2026 study: ground oyster shell and cuttlebone.
Both powders made the mix set noticeably faster and stiffen sooner after printing. Printed shapes deformed far less as powder content rose, roughly halving in the best mixes. Strength dipped against plain cement at first, then recovered as doses climbed and particles packed better. The results point to seafood waste as a practical printability aid.
