Assessing Pyrrhotite in Concrete

Ongoing
Objective - Develop a standard test method and a set of calibration reference materials to quantify pyrrhotite in concrete. What is the technical idea? Pyrrhotite (Fe 1-xS, where x = 0 – 0.2) is a common sulfide mineral exhibiting a brownish-bronze color with a metallic luster. Physical properties

Measurement Science to Assure the Performance of Green Concretes Project

Completed
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

Measurement Science to Assure the Performance of Innovative Concretes

Completed
Objective - To develop the measurement science needed to enable greater industry use of innovative concretes, such as 3D printing, more durable and limestone replacement concretes. What is the new technical idea? Manufacturing of cement and production/placement of concrete requires significant

Measurement Science Tools for Accelerated Weathering of Polymers Project

Ongoing
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

NIST Accelerated Weathering Laboratory: Metrology and Operations Project

Ongoing
Objective - To maintain, improve and expand capabilities at the NIST Accelerated Weathering Laboratory (AWL) and to use the facility to conduct safe, accurate and traceable aging experiments. Enable the technology transfer of the SPHERE technology to industrial stakeholders. What is the new

Physical Infrastructure: Connections

Completed
The NIST Physical Infrastructure Program will provide the critical measurement science needed to assess the condition of aging physical infrastructure and guide cost-effective strategies for its maintenance, repair, and replacement. Infrastructure management challenges in the U.S. have received

Properties of Sustainable Fresh Concrete Project

Completed
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

Reduced Ignition and Flame Spread with Nano-Engineered Foam Project

Completed
Objective: By 2015 2, to develop the measurement science that enables (1) design and manufacturing of low fire hazard soft furnishings through commercialization of low heat release, inexpensive, and EHS compliant nanoparticle-based fire retardant foam, (2) to assess the EHS attributes of

Repair Materials Project

Completed
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

Service Life Prediction of Filled Polymers Project

Ongoing
Objective: By FY2014, to develop and implement measurement science that will provide the technical foundation for service life prediction of filled polymeric materials exposed to compound environmental stressors, through quantitative tests and models applied to polymeric pipes, sealants, and

Surface Damage of Polymer Nanocomposites Project

Ongoing
Objective: Currently, it is impossible to accurately measurethe release of nanofillers from surface-damaged polymer nanocomposites. By 2014, this project will develop and implement measurement science to characterize, model, and predict surface damage and nanofiller release as a function of

Sustainable Engineered Materials

Ongoing
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

Virtual Cement and Concrete Testing Laboratory

Ongoing
The intended impact of this project is to enable a rapid and convenient virtual computing environment for evaluating and optimizing cementitious materials. Substantial savings in time, materials (purchase and disposal), human resources, and money can be achieved by reducing the number of physical
