<p>PROBLEM TO BE SOLVED: To enable the improvement plural performances, such as heat- insulation efficiency and noise absorbability, of a wood-wool cement board which is used as a building material. SOLUTION: When a wood-wool cement board 1 is produced by adding a cement 4 to a mixture of a wood-wool 2 with cork particles 3 and pressing the obtained mixture in a prescribed form, e.g. in the flat board-shaped form or in the block shaped form carbonized cork particles 3 having particle sizes of 1-30 mm are mixed with the wood-wool 2 in a weight ratio of the total cork to the total wood-wool of 5:100-50:100, and then, after adding a liquid cement 4, the mixture is kneaded. Further, the kneaded material is molded by using pressing machine and cured. Thereby, the wood-wool cement board 1 having a good performance modified by a cork property and effective as a building material can be produced.</p> |
