Inorganic board and method for producing the same
An object of the present invention is to provide an inorganic board suitable for achieving high specific strength and high freeze-thaw resistance as well as weight reduction and a method for producing the inorganic board. An inorganic board X1 according to the present invention includes a cured layer 11 that includes an inorganic 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. A method for producing an inorganic board according to the present invention includes a first step of preparing a first mixture through mixing of an organic reinforcement material and a hollow body smaller than the maximum length of the organic reinforcement material, a second step of preparing a second mixture through mixing of the first mixture, a hydraulic material, and a siliceous material, and a third step of forming a second mixture mat by depositing the second mixture.
