To provide a new industrial manufacturing method for various concrete products wherein a front thin layer to which a function of a high priced special functioning material, which developes the function even though it is mixed in cement, is given is provided, and the front thin layer is of a high quality and a continuous integral structure with a skelton part.

Cement mortar wherein a special functioning material is contained, improval of inseparability and adhesion in freshing and reduction of a crack generating risk and a whitening generating risk after manufacture are achieved, is sprayed by quick setting spaying and quick hardening mortar spraying and cast or the like on a shuttering surface becoming a finish surface after removing the mold to form a thin layer (primary layer). If necessary, ordinary coagulated adhesive mortar thin layer (secondary layer) is repeatedly executed thereon, all layers are integrated by placing a skelton concreate until the secondary layer is finished to be coagulated, and further the concrete product is manufactured by a series of processes wherein it is removed from the mold through stream curing.
