Abstract

A method includes using an element which includes a monoblock concrete body with a volume greater than 1 L and a surface porosity greater than 8%, which body includes in the body and/or on a surface thereof a compound having a BET specific surface greater than 100 m/g, and which element does not include a photocatalytic agent, to absorb from the atmosphere a gas selected from the group consisting of nitrogen oxides, carbon oxides, sulphur oxides, and ozone, or a volatile organic compound.
