Engineered Materials for Resilient Infrastructure Program

Ongoing
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

Advanced Cements and Concretes Consortium

Ongoing
For more information visit the NIST Carbon Capture and Carbon Sequestration project page. consortium goals The initial focus of this consortium is to evaluate, develop, and standardize methods to characterize and quantify the carbon and carbonates in new cements and concretes. Test methods to

Continuing Support of Cement Manufacturing

Ongoing
NIST SRMs for Portland cement and related materials are the de facto world standards for validation of analytical methods for testing of cement for compliance with manufacturing specifications and for qualification of laboratories throughout the supply chain, including cement plants, construction
Aggregate Concrete

Assessing Pyrrhotite in Concrete

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