NIST will advance measurement science tools to reliably assess the performance of sustainable materials for the manufacturing, construction, and transportation industries. These industrial sectors must meet demands for higher performance, multi-functionality, and for longer life to ensure a
Objective: This project will develop in situ measurements for characterizing stress transfer at the fiber-matrix interface in engineered nanocomposites, correlate stress transfer phenomenon and nanocomposite mechanical properties, and develop a database of mechanical properties as a function of
Objective: To develop and deliver the measurement science identified by industry for assuring the performance of Industrial-by-Product (IBP) low-carbon footprint concretes with up to 50% by mass of the cement replaced by IBPs by 2015.
What is the new technical idea? The industry average cement
Objective - Develop the measurement science tools (metrologies, standards, and guidance documents) for quantitatively evaluating the critical material properties and ensuring the desired field performance of repair materials for our nation's concrete infrastructure. What is the new technical idea
