Determining an Aggregate's Potential for Forming Alkali-Silica Reactivity (ASR) Gels in Concrete

Project Information

Project ID: 
FHWA-PROJ-11-0069
Project Abstract: 

The project will develop accelerated test methods to evaluate the alkali-silica reaction potential of an aggregateto form alkali-silica reactivity (ASR) gels if used in concrete. We want to try a technique using Raman spectroscopy to study the surface chemistry of the uncrushed aggregate. We also want to develop a technique for producing alkali-silica reaction gels on the surface, possibly with heat and pressure, and detect the presence of alkali-silica reaction gels using Raman spectroscopy. Detection of trace metals in the aggregate, which may be involved in the alkali-silica reaction gel reaction, would be determined by x-ray fluorescence spectrometry.
