Evaluation of coal fly ash in cementitious matrices

Abstract: ResumoThe addition of ash, initially classified as waste in cement matrices, is essential to achieve the requirements of National Policy of Solid Waste. However, technologies that enable such applications should be sought, especially when the material has adequate pozzolanic activity. The aim of this study was to verify the pozzolanic activity of fly ash from coal burning, from the aluminum manufacturing process, such as mineral admixture in mortars and conventional concrete. For that, physicochemical characte… Show more
