Abstract (en)
[origin: WO2012020012A1] The invention relates to an article comprising an article comprising an element made of a high performance concrete or an ultra high performance concrete, said element comprising a surface; and particles of calcium dihydroxide covering more than 60 % of the surface. It also relates to a process for the preparation of such an article comprising the coating walls of a mould with a demoulding composition comprising an aqueous solution comprising at least 1 % of a surfactant, introducing the concrete in the fresh state in the mould; and removing the article from the mould after the concrete sets.
