Abstract:
A source of sand is proposed as an educational tool to aid in the identification of silica mineralogies and textures susceptible to alkali-silica reaction. This particular silica sand originates in the southern portion of the state of Veracruz, Mexico, and exhibits a wide variety of lithologies, A thin section produced from a cross-section through a mortar bar subjected to ATSM C1260 Standard Test Method for Potential Alkali Reactivity of Aggregates (Mortar-Bar Method) exhibits plentiful examples of reactive silica.
