Document Type and Number:
Japanese Patent JP4126313
Kind Code:
B2
Abstract:
A block includes a block main body formed from an initial composition produced by mixing a first sand, a second sand, a ceramic aggregate, and cement. The mix rate of the sands and the cement is set so that the fineness modulus of the initial composition is 2.05 to 2.3. The block, which is manufactured under such a condition, includes a plurality of fine pores that form a continuous porous structure. Fine pores having a radius of 3.7 to 6500 nm have a fine pore volume of 0.02 to 0.04 ml/g and a specific surface area of 1.3 to 4 m2/g. The fine pores result in a gap rate of 18 to 28%.
