摘要:
A method for the treatment of a concrete surface includes at least partially covering the surface with a first coating which is substantially transparent and substantially impermeable to water; and at least partially covering said first coating with a second coating which is substantially transparent and photocatalytic; the surface having an average roughness Ra less than about 10 μm.
摘要:
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 m2/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.
