Multifunctional material for workability of geopolymeric system and its process thereof

A process for preparation of a material for addressing an issue of workability of a geopolymeric system comprising steps of:

• a) digesting rice husk in a range of 6.2% to 8.5% and NaOH in a range of 1.7% to 31% in water in a range of 62% to 85% at a temperature in a range of 50° C. to 100° C. for a time period in a range of 3 to 14 hours to obtain a digested mass,
• b) filtering the digested mass of step a) to obtain a slurry of the material in a range of 50% to 80% containing lignin, hemicelluloses, cellulose, and sodium silicate, wherein the sodium silicate has a size in a range of 40 to 100 nm.

A process for preparation of geopolymeric mortar/concrete cubes, the process comprising the steps of:

• a) adding a slurry of a material comprising rice husk in a range of 6.2% to 8.5%, NaOH in a range of 1.7% to 31%, and water in the range of 60 to 92% to a geopolymeric mortar/ concrete mix and water, the geopolymeric mortar/concrete mix including fly ash, and the slurry having a concentration of 0.25% to 1.5% with respect to the fly ash in the geopolymeric mortar/concrete mix, and casting mortar/concrete cubes from the geopolymeric mortar/concrete mix, b) curing the mortar/concrete cubes at a temperature in a range of 40 to 60° C. for a time period in a range of 46 to 50 hrs to obtain finished geopolymeric cubes.
