An Investigation of the Strength Properties of Fly Ash and Metakaolin-Based Geopolymer Mortars Containing Multi-Wall Carbon Nanotube, Nano Silica, and Nano Zinc

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