Title: Deciding method for external facing stone material for building construction
Inventor: TAKE TAKAO
IPC: E04C2/00
Filed: 1992-11-17
Abstract: PURPOSE:To previously decide change of properties of an external facing stone material by adding a predetermined quantity of hydrochloric acid to refined water, dropping it to the material, and observing it after a predetermined period. CONSTITUTION:Aqueous solution obtained by adding a predetermined quantity of concentrated hydrochloric acid to a quantitatively refined water and agitating the mixture is prepared, dropped on an entire surface of a stone material to be identified, the material is left to stand as it is until it is dried, and the surface of the material is observed after a predetermined period. As a result, the material in which unstable iron content is contained is discolored at its part, and the material in which the content is not contained is not discolored. Thus, since an external facing stone material for building construction can be previously identified in terms of potentiality of discoloring, the material is previously evaluated before the material is mounted in a structure, a quality of the material can be decided, the material can be effectively selected, and hence a claim after the construction, a post-contract compensation can be reduced.
