Abstract
The present study provides an experimental study for producing geopolymer paste and examines metahalloysite-based geopolymer with two types of alkaline solutions: sodium hydroxide (NaOH) and potassium hydroxide (KOH) mixed with sodium silicate. The nanomaterials were then added to reinforce the geopolymer by weight of metahalloysite (1%, 2%, and 3%) of these three types. The nanomaterials used are nano clay, Multi-walled carbon nanotubes, γ-Al2O3 and Hybrid. After aging for 28 days, the samples were tested under compression, hardness (shore D), Field Emission Scanning Electron Microscopy, Energy-dispersive X-ray spectroscopy, X-ray Diffraction, Fourier transform infrared spectroscopy, and Differential Scanning Calorimetry. Nano-hybrid exhibited the highest compressive strength and hardness. The morphology was homogeneous and without pores due to additives of nanomaterials that act as fillers in the matrix.
