Revolutionary Nacre-Inspired Cement Promises 17x Tougher, Eco-Friendly Future

2/24/2026

Summary

Story summary

Princeton University researchers developed a cement design inspired by nacre, achieving 17 times greater toughness than traditional cement.
The design uses multi-layered beams with hexagonal plates that mimic nacre’s structure to blend hard and soft materials, improving durability.
The approach could reduce the environmental impact of cement production, which contributes 8% of global greenhouse gas emissions.
Further refinements are needed before this technology can be widely adopted in construction.
