In this paper, geopolymer materials based on red mud and kaolin were prepared and characterized. Red mud and kaolin were mixed with different amount of alkaline activator and Ca(OH)2 at different temperature and curing time to form geopolymeric materials. Compressive strength of materials obtained was measured. The results show that the highest compressive strength of the materials was ~21 MPa. The presence of Ca(OH)2 component could make the C-S-H/C-A-S-H formation resulting the highly increasing in compressive strength of materials.
