Effect of Kaolin and Basalt Composition on Geopolymer Characteristics

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 stre...

Zusammenfassung:	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/cm 3 at 60 °C. Silica–alumina compounds dominated the constituent compounds of geopolymer concrete, and the phases formed were quartz, anorthite and muscovite.
