Abstract EN

Geopolymer is a binder material that was created as a result of efforts to decreasePortland cement's negative environmental effects.

Geopolymer concrete sharescertain properties with ordinary concrete, including brittleness.

Like ordinaryconcrete, geopolymer concrete, when exposed to stresses, cracks and fails underthese stresses.

The purpose of adding fibers to geopolymer concrete is toovercome the matrix's brittleness and enhance its strength (particularly flexuralstrength).

This study used metakaolin, a range of alkaline activators, anddifferent quantities of polypropylene fibers to produce geopolymer concrete.

Metakaolin's chemical composition, workability, density, flexural andcompressive strength of geopolymer concrete were all examined for the purposeof determining the effect of polypropylene fibers on geopolymer concrete.

Polypropylene fibers were used to make the mixes, which were then added to themix at various percentages of 0 % , 0.5 % , and 1 % of the total volume ofconcrete.

The results of the experiments showed that increasing thepolypropylene fiber content to 0.5 % boosts the compressive strength ofgeopolymer concrete.

On the seventh day, the compressive strength increased to21 % .

The density of geopolymer concrete was increased by addingpolypropylene fibers, and there was a decrease in the workability with differentfiber Geopolymer is a binder material that was created as a result of efforts to decreasePortland cement's negative environmental effects.
