Hybrid geopolymer-cement coating mortar optimized based on metakaolin, fly ash, and granulated blast furnace slag

The use of wastes for new binders aims to reduce the environmental impact caused by the manufacture of Portland cement (PC) given the advance of urbanization. In this work, the main effects of the use of Geopolymer Cement (GC) in partial replacement to PC in mortars for coating were investigated. The GC was obtained from mixtures of industrial wastes, fly ash (FA), granulated blast furnace slag (GBFS), and metakaolin (MK), activated by a...
