Sintered geopolymer compositions and articles
The present invention relates to geopolymer composition, sintered geopolymer articles from the geopolymer composition and processes for manufacturing sintered geopolymer articles from the geopolymer compositions. The invention provides a process of producing a sintered geopolymer article having a matrix containing sintered geopolymer composition, said process comprising the steps of: (1) forming a geopolymer composition comprising at least one aluminosilicate precursor, an alkali activating agent and water, wherein in the geopolymer article, the aluminosilicate precursor particles are at least partially coated by the alkali activating agent; and (2) firing the geopolymer article to sinter the geopolymer composition, wherein the alkali activating agent is capable of at least partially activating and dissolving the aluminosilicate precursor particles during at least a portion of the sintering phase of the geopolymer composition and wherein the sintering phase of the geopolymer composition includes an alkali-activated sintering stage.
