摘要:
The present invention relates to a method for preparing a controlled porosity geopolymer with a step of dissolution/polycondensation of an aluminosilicate source in an activation solution comprising the following successive steps: (a) defining a characteristic of the porosity of the geopolymer to be prepared; (b) determining a value or an element for a parameter chosen from the total amount of water, the total amount of silica, the compensation cation, and the particle size distribution of the optional silicate components, which makes it possible to obtain the characteristic defined in step (a); and (c) selecting said value or said element predetermined in step (b). The present invention relates to a geopolymer capable of being prepared by said method and also to the various uses of said geopolymer.
