Özet:

 


This paper presents the results of an
experimental program to determine the properties of glass fiber reinforced
geopolymer mortar which is a mixture of fly ash, alkaline liquids, fine
aggregates, and glass fibers. The effects of inclusion of glass fibers on
density, compressive strength, splitting tensile strength, absorption and
sorptivity of hardened geopolymer composite (GPC) was studied. Alkaline liquid
to fly ash ratio was fixed as 0.33. NaOH and NaSiO3 solutions were
used as alkaline liquids for activation of fly ash. The alkaline liquid
combination ratio of 2.5:1 were used for Na2SiO3:NaOH.
Glass fiber was added to the mixes in 0.2%, 0.4%, 0.6%, 0.8%, 1.0% and 1.2% by
volume of mortar. A curing regime of 48 hours with 60 ˚C temperature was
applied. The experimental results indicated that inclusion of the glass fibers
resulted in a decrease in the workability, yet, an improvement in compressive
strength and splitting tensile strength of fly ash based GPC was obtained by increasing
the fiber content. However, the inclusion of glass fiber did not indicate a
remarkable change in the water absorption and sorptivity of GPCs.
