Reviewed by Bethan DaviesResearchers have found that recycled concrete powder (RCP) can replace up to 50 % of Portland cement in 3D-printed mixes—reducing carbon emissions by over half while maintaining printability. The study evaluated two types of RCPs in cementitious pastes using rotational rheometry, isothermal calorimetry, and life cycle assessment (LCA), along with printability tests to assess extrudability and buildability.

Reviewed by Lily Ramsey, LLMA recent article in Buildings introduced a numerical model of an 18-story reinforced concrete frame with a core tube and a double-layer seismic isolation system. Designed using YJK (3.0) and simulated in ABAQUS, the model was used to evaluate how high-rise buildings respond to three different seismic waves. ​​​​​​​BackgroundTo minimize earthquake damage, engineers have developed various structural systems based on seismic isolation principles.

Reviewed by Lexie CornerA recent article published in Applied Surface Science Advances describes the bioprinting of nanostructured patches composed of sodium alginate (NaAlg), polyvinyl alcohol (PVA), and indocyanine green (ICG), either freely dispersed or encapsulated in liposomes. Three formulations were evaluated using scanning electron microscopy (SEM) and atomic force microscopy (AFM) to investigate their surface morphology and structural characteristics.

Reviewed by Bethan DaviesIn a notable advance for smart construction materials, researchers have developed a bio-inspired cement–polyvinyl alcohol (PVA) composite (CPC) that significantly boosts thermoelectric efficiency, opening the door to self-powered buildings and infrastructure. Published in Science Bulletin, the study introduces a composite that mimics the layered stem structure of plants.

Reviewed by Lexie CornerA recent article in Scientific Reports looks at how gold ore tailings (GOTs) and recycled coarse aggregates (RCAs) can be used as substitutes for river sand (RS) in geopolymer concrete (GPC). The study focused on how durable this type of concrete is, especially when exposed to sulfates and chlorides.
