3D‑Printed Diatomaceous Concrete That Absorbs Carbon: Innovative and Ready for Ecotox Integration
University of Pennsylvania engineers have unveiled a groundbreaking 3D‑printed concrete that absorbs up to 142% more CO₂, achieves structural strength comparable to traditional mixes, and uses ~60% less material. Leveraging diatomaceous earth’s porous microstructure and optimized geometry, this innovation marks a leap toward low‑carbon building materials Facebook+5Penn Today+5sciencesprings+5.
🧬 How It Works
- Diatomaceous earth (DE) as a CO₂ sponge:
DE is full of microscopic, sponge-like pores formed from fossilized algae. When blended into concrete, these pockets trap CO₂ during curing, enhancing carbon uptake and strengthening the structure Penn Today+1sciencesprings+1. - Optimized porous geometry:
Utilizing triply periodic minimal surface (TPMS) designs—structures inspired by bones and coral—allows the mix to retain 90% of normal compressive strength while increasing CO₂ absorption by 30% and cutting material use by 60% sciencesprings+1Penn Today+1. - 3D printing advances:
The high-porosity mix flows smoothly through printer nozzles yet rapidly stabilizes and cures, maintaining integrity while enabling complex architectural designs Wikipedia+2sciencesprings+2Penn Today+2. - Environmental and ecological benefits:
Beyond carbon capture in air, this material shows promise for marine applications, such as reef restoration or oyster bed structures, due to its porosity and ecological compatibility UPenn EII+2Reddit+2Penn Today+2sciencesprings+1Penn Today+1.
