Some people like plastic Christmas trees; others prefer real wood and needles. This year, NIST is printing a tree out of concrete. The tree is not only festive
The National Construction Safety Team has reached an important milestone in its investigation into the 2021 partial collapse of Champlain Towers South.
Objective To improve residential and industrial building energy efficiency by decreasing measurement uncertainties of the thermal resistance of insulating materials and develop measurement techniques for innovative insulation materials and systems using PCMs. Technical Idea One of the most cost
Objective - Provide the industry with measurement science tools to predict whether a concrete can be pumped, with SRMs (Standard Reference Materials) to calibrate concrete rheometers and with tools for quality control in the field.
What is the new technical idea? Fresh concrete is intended a
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
Objective - Develop a U.S. resource for service life prediction by delivering a suite of measurement science tools including publically available data sets, statistical models, validation data, and geographically specific predictions based on validated statistical models. This resource will be the
