Abstract
Geopolymer powder prepared through pre-curing and pulverization showed great potential to produce one-part-mixing geopolymers as well as high flexural strength geopolymer ceramics. The one-part-mixing geopolymers were prepared by mixing geopolymer powder with water while the geopolymer ceramics were prepared by powder metallurgy and sintering. The one-part-mixing geopolymers achieved a compressive strength of 10 MPa after 28 days with formation of geopolymer precipitates in conjunction with zeolite phases. Despite the lower strength, they remained stable and did not disintegrate when immersed in water. Besides, the geopolymer ceramics exhibited high flexural strength (90 MPa) after sintering at 1200 °C as result of nepheline formation.
