    摘要: Provided is a building material (10) 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 (10), including: a first step of curing a core layer (1) 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 (1); a second step of dispersing a surface layer (2) material including a hydraulic material, and a silica-containing material, to form an unfoamed surface layer (2); a third step of stacking the foamed core layer (1) on the unfoamed surface layer (2), to form a stack including the unfoamed surface layer (2) and the foamed core layer (1); and a fourth step of pressing and curing the stack, and a building material produced therewith.

    摘要: There is provided a cutting tool having high wear resistance and fracture resistance by reducing the occurrence of thermal cracking on a cutting edge even during a cutting process of a heat-resistant alloy in which the cutting edge reaches high temperatures. The cutting tool is made from a cemented carbide that is composed mainly of a WC phase and contains 11.5-12.5% by mass of Co and 0.2-0.6% by mass of Cr in terms of Cr 3 C 2 . The WC phase has a mean particle size of 0.85-1.05 µm, an antimagnetic force (Hc) of 13.0-16.0 kA/m, and a Rockwell hardness (HRA) of 89.5-90.5.
