摘要

PROBLEM TO BE SOLVED: To provide a two-layer panel which is excellent in fire resistance and has sufficient strength and freeze damage resistance, and a method for manufacturing it. SOLUTION: The two-layer panel 10 is manufactured by integrating a base layer 11 and a surface layer 12. The base layer 11 is composed of a compound in which an organic material is used as an aggregate or a bulk filler and a hydraulic intimate mixture is mixed therewith.
