Abstract:
The objective of the invention is to provide a mineral board suitable for achieving a high specific strength, a high resistance to freeze-thawing, and weight reduction, and to provide a production method therefor. The mineral board X1 of the present invention comprises a cured layer 11 containing a mineral cured matrix, an organic reinforcement material dispersed therein, and a hollow body that is attached to the organic reinforcement material and is smaller than the maximum length of the organic reinforcement material. The mineral board production method of the present invention comprises a first step of obtaining a first mixture through mixing of the organic reinforcement material and the hollow body that is smaller than the maximum length of the organic reinforcement material, a second step of obtaining a second mixture through mixing of the first mixture, a hydraulic material, and a siliceous material, and a third step of depositing the second mixture to form a second mixture mat.
