The connection between eco and building materials can be
successfully accomplished by using geopolymers. Geopolymers are
composite materials made of long chain molecules incurred by
polymerization of geopolymer binders. Usually, geopolymers are defined
as a solid and stabile aluminosilicate materials, made of industrial
byproducts and liquid solutions such as NaOH and Na2SiO2.
…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. Mass percentages of ladle slag, wood ash, red
mud and waste glass in respect to the total mass of the binder was 0 to
20%, varied in 5 % steps of replacement. Mass percentage of ground
granulated blast furnace slag in respect to the total mass of the binder
was ...0 to 100%, varied in steps of 20 % steps of replacement. All batches
were made by using binder with the particle size smaller than 0,09 mm.
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. It has been proved that
geopolymer mortars and concretes might be used as a construction
building materials. Furthermore, because of their physical-mechanical
characteristics and durability properties, they can be alternative solution
for the traditional mortar and concrete mixtures.
