METHOD FOR PRODUCING A MACROPOROUS AND MESOPOROUS GEOPOLYMER, WITH CONTROLLED POROSITY

摘要

The invention relates to a method for producing a macroporous and mesoporous geopolymer and especially a geopolymer foam, comprising the following successive steps: (1) preparing a composite material comprising a geopolymer matrix and an organic liquid; then (2) eliminating said organic liquid by a treatment selected from the group consisting of heat treatment, oxidation treatment, photodegradation treatment and extraction using a supercritical fluid or ultrasounds.
