<p>The invention provides a building board excellent in water absorption resistance, dimensional stability and/or frost damage resistance, and a method for producing the same. The building board is produced through the following processes: preparing a slurry by dispersing a cement-based hydraulic material and a refined fiber reinforcing material into water, adding a saturated carboxylic acid to the slurry, and then the slurry is subjected to the steps of sheetmaking, dehydration, pressing and curing. The building board comprising a refined fiber reinforcing material at 1-30 weight % based on the total solid content and a saturated carboxylic acid at 0.1-2.0 % based on the total solid content.</p> |
