Since the mid-1990s, a type of steel column that commonly features slender cross-sectional elements has become more prevalent in buildings along the West Coast
Damage to concrete structures in residential and commercial construction in central Connecticut have been attributed to the iron sulfide mineral pyrrhotite
Using a complementary approach of experimental measurements and detailed finite element analysis, we will develop more realistic yet computationally efficient
Prior efforts at NIST demonstrated the feasibility of quantitative service life prediction by linking the field and laboratory for an unfilled polymer. This
Due to intensified pricing pressure and rapid growth of photovoltaic (PV) technology, low cost and emerging polymeric materials are being used increasingly in
Retrofit and repair of structures occur under differing circumstances but are both necessary to improve existing building stock and increase resilience of
Portlandite (calcium hydroxide: CH: Ca(OH)2) suspensions aggregate spontaneously and form percolated fractal aggregate networks when dispersed in water. As a
This tutorial is a guide on how to implement the NIST infiltration correlations (Ng et al., 2021) into EnergyPlus building energy simulation software for the US

Accurate quantitative data on cement and clinker microstructure images can prove valuable for
(Return to Cement Hydration and Degradation Modeling Software) A set of C and Fortran computer programs have been developed for computing the permeability of
(Return to Cement Hydration and Degradation Modeling Software) The purpose of this form is to provide an estimate of the electrical conductivity (S/m) of the
In the artificial ultraviolet (UV) weathering of materials, a need exists for weathering devices that can uniformly illuminate test specimens with a high level
The Large Aperture Scanner (LAS) scans a radar transceiver over a 5 meter by 20 meter aperture. Image reconstruction techniques enable a three-dimensional
The 1-meter guarded hot-plate apparatus measures thermal conductivity of building insulation. This facility provides for absolute measurement of thermal
