Abstract
A manufacturing process that includes spray-drying a liquid composition based on liquid residues derived from a chemical extraction of clinker to form a material with a high specific surface area. Also, a material based on clinker residues having a high specific surface area ranging from 200 m2.g−1 to 900 m2.g−1 and a mesopore size ranging from 2 nm to 50 nm. Further, the use of a material having a high specific surface area for the absorption of pollutants species.
