Damage to concrete structures in residential and commercial construction in central Connecticut have been attributed to the iron sulfide mineral pyrrhotite
The use of thermal insulation is a primary approach to reducing heating and cooling loads in buildings, which account for 42 % and 24 % of energy consumption in
In spite of advances in materials and construction technologies, our nation's civil infrastructure remains in a state of serious decay. The 2013 American
The unceasing quest for more durable, more environmentally friendly, and less expensive construction materials is compelling the concrete industry to adopt
An effective strategy for making a more "green" concrete is to replace the portland cement (the binding component with large energy and CO2 footprints) with
Due to intensified pricing pressure and rapid growth of photovoltaic (PV) technology, low cost and emerging polymeric materials are being used increasingly in
There is pressure on U.S. industry to develop innovative solutions to meet increasing customer and regulatory demands for sustainable manfactured materials
Accurate prediction of the time to failure (service life) for polymeric materials is needed to support precise life cycle costs and sustainability assessments
Using a complementary approach of experimental measurements and detailed finite element analysis, we will develop more realistic yet computationally efficient
The construction industry is becoming increasing reliant on pumping for the placement of concrete; thus, implying that a concrete must have the desired early
Performance-Based Earthquake Engineering (PBEE) has provided a probabilistic framework to predict the response of the structural systems by incorporating the
This research will enable commercialization of a reduced flammability, inexpensive, and EHS[1] compliant polyurethane foam and a high smoldering reference foam
In certain regions of moderate seismicity, particularly in the central and eastern United States (CEUS), member sizes of the seismic force-resisting systems
This project will utilize chemical spectroscopy of stressed composites to quantify the magnitude and mode of stress transfer at the fiber-matrix interface in
Prior efforts at NIST demonstrated the feasibility of quantitative service life prediction by linking the field and laboratory for an unfilled polymer. This
Surface damage caused by environmental and/or mechanical stresses can lead to the release of nanofillers incorporated within polymer nanocomposites, leading to
