摘要
The object of the present invention is the manufacture of a cementitious item through mold casting of a fluid composition comprising a hydraulic binder, one or more aggregates, an anti- shrinkage agent, a superplasticizer agent and water. The item (1) according to the invention comprises at least a first portion (15) in relief with respect to at least one second portion (25) and wherein the surface roughness of said first portion (15) is less than the surface roughness of said second portion (25). According to the invention, said first portion (15) is obtainable from the solidification of said fluid composition in contact with a polymeric material applied to the surface of a half-mold (10) of said mold, while the second portion (25) is obtainable from the solidification of the fluid composition in contact with a portion of an adhesive film (20) applied to the polymeric material or to the surface of said half-mold (10).
