Process for the preparation of geopolymeric functional materials in a solid form

摘要

The present invention provides a process for the preparation of tailored precursor materials in a solid powder form, useful for geopolymeric system containing pentavalent silicon complexes in a solid powder form. The raw materials used are fly ash, sodium hydroxide, and rice husk with and without sodium silicate. The tailored precursors so obtained in solid powder need only water at site, instead of highly alkaline solution for obtaining the cementitious geopolymeric materials.

主权项

1. A tailored precursor material composition in solid form for geopolymer material comprising fly ash (59-91%), sodium hydroxide (11-15%), rice husk (0.8-11%) and optionally sodium silicate (0-29%).
