Aluminosilicate system based on alkali activation of industrial by-products reinforced with wollastonite microfibers
Original language description
Portland cement-based products are the most commonly used building materials. However, it is well known that the production of OPC not only consumes significant amount of natural resources and energy but also releases high quantity of carbon dioxide (CO2) to the atmosphere. Purpose of this work is to develop material similar to Portland cement-based concrete, which would be convenient both in terms of energy and environmental friendliness. This article presents preparation, composition and properties ofinorganic aluminosilicate polymer, called geopolymer, synthesized from an alkali activation of fly ash/slag mixtures. In the research, effects of different kinds of fly ash from Czech power plants and different dosage of slag and alkali activators thatinfluence compressive strength of hardened geopolymer pastes were discussed. Relatively small flexural strength after 28 days was enhanced with wollastonite microfibers. The study of the microstructure was based on XRD and SEM-EDX analyse
