Self-healing cement could transform industry
A self-healing cement developed by Pacific Northwest National Laboratory can outperform conventional concrete, offering a potentially pollution-preventing technology for the growing geothermal industry. This game-changing combination uses a flexible ingredient, a polymer, to repair fractured surfaces and fill cracks, minimizing mechanical failure risks and offering a sustainable energy source. Chemist Carlos Fernandez and his team in collaboration with Simerjeet Gill of Brookhaven National Laboratory, detail the polymer's healing properties and how it can improve the mechanical performance of cement in a paper, "Insights into the physical and chemical properties of a cement-polymer composite developed for geothermal wellbore applications," in Cement and Concrete Composites.
