| 摘要 | Provided is a building material that is lightweight, exhibits excellent formability, and is inhibited from being damaged during transportation, and a method for producing the same. Specifically, provided is a method for producing a building material, including: a first step of curing a core layer material including a hydraulic material, a silica-containing material, and an aluminum powder, to react the aluminum powder and form bubbles, and incompletely hardening the hydraulic material and the silica-containing material, to form a foamed core layer; a second step of dispersing a surface layer material including a hydraulic material, and a silica-containing material, to form an unfoamed surface layer; a third step of stacking the foamed core layer on the unfoamed surface layer, to form a stack including the unfoamed surface layer and the foamed core layer; and a fourth step of pressing and curing the stack, and a building material produced therewith. | ||||||
