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 agencies are funding 20 projects to be conducted across 24 institutions through the Disaster Resilience Research Grant (DRRG) program, which they manage
Engineers and technicians at the National Institute of Standards and Technology (NIST) spent months meticulously recreating the long concrete floors supported
Objective - To maintain, improve and expand capabilities at the NIST Accelerated Weathering Laboratory (AWL) to conduct safe, accurate and traceable aging experiments, develop materials degradation databases, and to transfer the SPHERE technology to industrial stakeholders. What is the new technical
NIST develops benchmark materials, measurements, data, and models to accelerate innovation in and validate performance of materials and technologies for carbon capture and carbon sequestration in building materials.
Objective - To develop and promote new ASTM standard test methods and ASTM specification limits for cement and concrete materials based upon a comprehensive assessment of mineralogical, chemical and textural properties. What is the new technical idea? Current cement specifications are based on
