Uticaj industrijskih nusproizvoda na svojstva geopolimernih kompozita na bazi elektrofilterskog pepela

Abstract

Geopolymers are materials made of chain molecules incurred by polymerization of geopolymer binders. geopolymers are defined as a solid and stabile aluminosilicate materials, made of industrial byproducts and liquid solutions. The experimental part of the dissertation, contains the results of physical-mechanical, microscopic and durability properties of geopolymer mortars and concrete based on fly ash. For the purpose of determining the effect of different byproducts on characteristics of geopolymer mixtures, 24 batches of mortar and 8 batches of concrete were made and tested. (converter slag, wood biomass ash, red mud, and waste glass) in the amount of 5% - 100% with different steps of replacement in relation to to the binder mass. The samples of geopolymer mortar and concrete were cured at an ambient temperature According to the test results some recommendations for the possible application of fly ash and other industrial byproducts for making geopolymer mortars and concretes are made. Tested materials might be used as construction building materials and according to their physical-mechanical characteristics and durability properties, they can be alternative solution for the traditional mortar and concrete mixtures.
