The evaluation of geopolymer properties prepared by alkali activation of black coal ashes with high content of loss on ignition [PDF]
, 2010 The utilization of fly ashes in Slovakia is lower than in other countries and dumping of fly ashes prevails. The dumping changeschemical and phase composition of fly ashes and so it decreases possibilities for their utilization. Fly ashes are mainly used

Portland cement versus hybrid cement and geopolymers: performance at high temperatures
, 2015 This paper reports on a comparative study of the mechanical performance at high temperatures of a commercial Portland cement (CEM I 42.5 (OPC)), a hybrid cement (CEM HYC = 30% clinker + 32.5 % BFS + 32.55 % FA + 5 % alkaline activator) and a geopolymer (fly ash-activated with waterglass solution). Two types of mechanical tests were conducted on samples

Elaboration of geopolymer cement based on dredged sediment
Journal of Materials and Engineering Structures, 2019 This work aims to study the feasibility of making a geopolymer cement based on dredged sediments, from the Fergoug dam (Algeria). Sedimentary clays were characterized before and after calcination by X-ray diffraction, ATG / ATD, spectroscopy (FTIR) and XRF analysis.
