Assessing Pyrrhotite in Concrete

Ongoing
Objective By 2026, develop a standard test method, a set of calibration reference materials to quantify pyrrhotite in concrete; document the pyrrhotite/aggregate/concrete reactions and rates so that the most deleterious reactions can be efficiently reduced or eliminated; and evaluate proposed...

Assessing Steel Corrosion Risk in Innovative Cement Concretes

Ongoing
Objective Develop new measurement standards to assess the corrosion of steel embedded in new and existing infrastructural assets. Technical Idea The Assessing Steel Risk in Innovative Cement Concretes project will combine characterization of concrete pore solution chemistry, electrochemical...

Assuring the Long-Term Performance of Additively Constructed Structures

Ongoing
Objective Develop the metrology, best practices, and standardized test methods that are needed to develop building codes that can ensure adequate structural performance throughout the intended service lifetime of AC structures. Technical Idea [Focus on the Layer Interface] These problems can be...

Engineered Materials for Resilient Infrastructure Program

Completed
Objective - To develop and deploy measurement science to reliably assess the current and future performance of engineered materials in support of resilient infrastructure given exposure to chronic (e.g., materials degradation) and episodic (e.g., earthquakes) hazards. What is the technical idea? To...

Hydration Reactions in Microstructures Project

Completed
Objective - Generate and publish reaction rate data and enhanced computer modeling tools to better understand and predict the rates of microstructure development and phase interactions in portland cement concrete binders. What is the new technical idea? Reflection digital holographic microscopy (DHM...
