To provide a typically plate-shaped or sheet-shaped inexpensive web product that is prepared on a large scale and using cheaper raw materials that have not been used, with the web being tenacious and non-toxic when used as construction parts of houses, and capable of being discarded under the ground so as to be readily decomposed by bacteria and enzymes, and further capable of being burnt at lower temperatures preventing generation of toxic substances. The web is made from a non-woody fiber pulp that is any one of fibers originating from gramineous, palmaceous and polygonaceous plants, or any mmixture of them. The graimineous plants are of a self-reproducing nature and the polygonaceous plants are any buckwheat. The web of this composition is rendered sheet-shaped before hot-pressed or dried to give concrete formwork articles, wallpapers or the coverings for Japanese sliding doors.
