Alkali-Silica Reaction and High Performance Concrete
- http://fire.nist.gov/bfrlpubs/build95/art004.html
- Answers the question if high-performance concrete is susceptible to alkali-silica reaction. The paper contains details on the alkali-silica reaction mechanism and the factors influencing it as well as an overview on available test methods (ASTM C1260 and C227). Besides an abstract the fulltext is available as PDF (24 pages, 1.3 MB).
Modified Slump Test to Measure Rheological Parameters of Fresh Concrete
- http://fire.nist.gov/bfrlpubs/build98/art058.html
- The ease of placement of concrete depends upon at least two physical properties, the yield stress and plastic viscosity. Currently the most common field test is the slump test, and it is related only to the yield stress. Therefore, a simple field test method intended to provide an evaluation of the two Bingham rheological parameters, yield stress and plastic viscosity, was developed. Description of apparatus and test procedure.
Stress Due to Alkali-Silica Reaction in Mortars
- http://fire.nist.gov/bfrlpubs/build97/art019.html
- A test method and test apparatus is presented. It does not measure the length change but measures the stress generated by the swelling of the gel. The force required to prevent expansion is measured over time while the specimen and frame are immersed in a solution of 1-N NaOH at 50°C. With some test results.
Technical Dictionary of European Mortars - EMODICO

- A compendium of terms and definitions concerning mortar products and their use, available in English, French, German, Spanish and Portuguese. The European Mortar Industry Organization (EMO) prepared this document in order to make technology exchanges easier.
Visible Cement Dataset
- http://visiblecement.nist.gov/
- A collection of three-dimensional data sets of hydrating cement, Plaster of Paris, and common brick material, all obtained using x-ray microtomography at the European Synchrotron Radiation Facility in Grenoble, France. Each data set includes a description of the sample, the raw 3-D data, and several two-dimensional images extracted from the raw data. Also included are several C utility programs useful for exploring these datasets.
