Abstract

Abstract: The effect of variations in the composition of kaolin and basalt on the geopolymer characteristics was carried out. The drying time was 4 h for cubic samples at 40, 50 and 60 °C and 9 h for cylindrical samples at 70 and 90 °C. The best geopolymer was 4 cylinder at 90 °C, which had a compressive strength of 8.075 MPa. The density of 2 cube geopolymer ranged as 26–1.94 g/cm3 at 60 °C. Silica–alumina compounds dominated the constituent compounds of geopolymer concrete, and the phases formed were quartz, anorthite and muscovite.
