There is provided a method for forming a pattern or a shape in a concrete wall structure, the method comprising: mixing a cement about 100% by weight and silicon about 50% by weight to form a mixed silicon; inserting the mixed silicon into a forming frame; pressing a pressing member onto the first surface and removing the pressing member from the first surface; attaching the forming frame onto the form; placing and curing a concrete to the surface of the mixed silicon in which the shape or pattern is defined; and removing the mixed silicon from the cured concrete, thereby to obtain a concrete wall structure having the three-dimensional pattern or shape formed therein.
