Abstract
The invention concerns dry particulate compositions for forming a geopolymer, comprising an aluminosilicate containing mineral, a polymeric additive, an alkali metal silicate, and an alkali metal hydroxide. The invention concerns processes of making geopolymers, the geopolymers, as well as the use of the dry particulate compositions in the formation of geopolymers.
Claims20
A dry particulate composition for forming a geopolymer, the dry particulate composition comprising:
- an aluminosilicate-polymeric additive mixture comprising
- an aluminosilicate-containing mineral
- an olefinic thermoplastic polymer as a polymeric additive,
- an alkali metal silicate, and
- an alkali metal hydroxide;
- wherein
- an amorphous phase content of the aluminosilicate-polymeric additive mixture is at least 30% by weight, and
- the result of a BET specific surface area in m2/g of the aluminosilicate-polymeric additive mixture multiplied by the amorphous phase content of the aluminosilicate-polymeric additive mixture falls in the range 1 to 10.4.
