Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

BTEX EMISSIONS FROM BioCo2 BONDED MOULDING SANDS

Metallurgy and Foundry Engineering, 2013
The aim of the research was to determine the volume of BTEX emission (benzene, toluene, ethylbenzene and xylenes) from BioCo2 bonded moulding sands. BioCo2, a new polymer binder, is a water solution of two - component polymer composition (polyacrylic acid and dextrin).
