Princeton engineers develop crack-resistant cement composite
AI Article Summary
Researchers at Princeton University have developed a new crack-resistant cement composite inspired by nacre, also known as mother of pearl. This composite consists of alternating layers of cement paste and thin polymer, significantly enhancing ductility and resistance to cracking compared to traditional materials. The system mimics nacre's structure, incorporating aragonite tablets for strength and biopolymers for flexibility, achieving a composite 19 times more ductile and 17 times tougher than standard cement. This innovation could revolutionize the development of stronger building materials.
What This Means for Canadian Contractors
This project shows how innovative materials inspired by nature can enhance construction practices. For Canadian builders, this means potential advancements in creating more durable structures with fewer maintenance issues, particularly in harsh climates. Such improvements could also impact project timelines positively by reducing the incidence of repair work and extending the lifespan of the materials used.
