Quartzite Mining Waste: Diagnosis of ASR Alkali-Silica Reaction in
The main objective was to determine the deleterious potential of quartzite mining tailings subjected to different ASR alkali–silica reaction tests. The studies included petrographic analysis, chemical analysis of cements, expansion tests in mortar bars and concrete prisms, and microstructural analysis. Petrographic analysis of quartzites This is because foliated quartzite slabs are obtained directly from the rock mass, following standards of thickness and length, and the waste generated in mining and processing of these materials becomes a problem for entrepreneurs, with negative environmental impacts, such as: landscape disfigurement; changes in the natural shape of the relief; siltation of Quartzite Mining Waste: Diagnosis of ASR Alkali-Silica Reaction in
