PURPOSE:To obtain a concrete material which improves decorative properties and can control generation of a warp and crack, by a method wherein a plurality of cement slurries whose colors are different from one another are cured and molded by adjoining them to one another on a surface layer including also the surface. CONSTITUTION:Cement slurries 1 whose colors are different from one another are cast at intervals on a surface layer and then a general cement slurry 2 such as Portland cement is cast calmly into a vacant part of a concrete shuttering 3. Then it is constituted so that the former cement slurry 1 and the latter cement slurry 2 do not mix up with each other. After casing they are demolded after they have been cured sufficiently, a concrete material A is obtained by performing curing, hardening and drying further.
