Formation of one-part-mixing geopolymers and geopolymer ceramics from geopolymer powder [PDF]

Construction and Building Materials, 2017
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 ...
