37、: 24 h in room temperature (60 to 86F (15.5 to30C) water or5hinboiling water. (Different time intervals arespecified for structural tile and other products.) The resulting absorp-tions are termed cold water absorption and boiling water absorption.Absorption values are used in brick and tile standard

Absorptions areindicators of the extent of firing during manufacture as well as beingindicators of durability.body color, nthe range of color obtained when materialsused to form the brick react to the effects of firing tempera-ture

39、 and atmosphere.DISCUSSIONThere may be additives in the body to produce a desiredcolor. When no materials are added to the surface of the brick and theunit is not flashed when fired, the body color is also the through-bodycolor, a surface feature.brick, na solid or hollow masonry unit of clay or sha
