Özet
In this study, the mechanical properties of geopolymer mortar composites containing
different nanomaterials were investigated. Fly ash (FA) and metakaolin (MK) were
used as binders in geopolymer mortar samples. Sodium silicate (Na2SiO3) and
sodium hydroxide (NaOH) solutions (12 M) were used as alkali activators. Multiwalled carbon nanotubes (MW-CNT), nano-SiO2 (NS), and nano-ZnO (NZ) were
used in the study. Geopolymer mortar samples without nanomaterials were
determined as control samples, and geopolymer mortar samples containing 0.5% by
weight of MW-CNT, NS, and NZ were prepared. All prepared samples were cured
at 20±2 °C in laboratory conditions for 7-day and 28 day. The curing geopolymer
mortar samples were subjected to compressive strength and flexural strength tests.
As a result of this study, the mechanical strength of all geopolymer mortar samples
containing nanomaterials increased compared to the control samples. The highest
compressive strength and flexural strength were obtained from geopolymer mortar
samples containing MW-CNT. These samples were followed by geopolymer mortar
samples containing NS and NZ, respectively.
