Abstract
Nanomaterials, which are inferable from their exceptional properties, are known to enhance the microstructure of concrete, upgrades the fresh and strengthened state characteristics of cement concrete, and are broadly utilized in cementitious ingredients. The primary goal of this investigation is to compare the mechanical properties of geopolymer concrete (GPC) based on fly ash (FA) and ground granulated blast furnace slag (GGBFS) to that of ordinary portland cement concrete using Nano-Alumina. The Nano-Alumina particles are added to the GPC and OPC concrete at dosages of 1%, 2%, and 3% by weight of the binder, respectively, and the counterparts of the same test samples without Nano-Alumina are prepared. All the Geopolymer concrete samples were cured at room temperature and had a consistent liquid/binder ratio of 0.48. The current study also proposed using Quartz and Feldspar (QF-mineral sand) as fine aggregate in all the mixtures due to the natural depletion of river sand. The experimental results reveal that inclusion of 2 wt% Nano-Alumina particles was optimal for increasing the mechanical properties of OPC concrete and GPC.
