PROBLEM TO BE SOLVED: To provide a technology for molding a product having a property similar to FRP, where a product with a weak alkalinity prepared from an inorganic composition which does not cause a waste disposal problem, having a comparatively low specific gravity, high toughness, and a moldability capable of forming a lightweight and thin three-dimensional curved surface is molded under an ordinary temperature and pressure for a short time without mixing a calcium compound easily dissolvable in water and without using a strong acid which accelerates rusting. SOLUTION: The inorganic composition for molding or building is composed of magnesium oxide of 20-60 wt%, magnesium chloride of 5-40 wt%, aluminum oxide of 5-40 wt%, and silicon dioxide of 5-30 wt%.
