Construction Technology is Changing
Research was conducted at Princeton University, where scientists analyzed why brittle materials like concrete and ceramics break easily and how this can be prevented.
TL;DR
- Researchers developed a new type of concrete that is more resistant to cracking and slows fracture propagation.
- The inspiration for the material came from the layered structure of mother-of-pearl, which consists of hard mineral layers and softer connecting material.
- The new composite material uses a cement paste for the hard component and an elastic polymer for the softer layers, arranged in thin layers within the structure.
- This structure forces cracks to change direction and consume more energy, increasing material resistance.
- Potential applications include longer-lasting and safer buildings, bridges, and infrastructure, leading to reduced maintenance costs and increased safety.
