Abstract: A board of calcium silicate crystals, characterized in that the board is composed of a plurality of layers of laminated thin sheets, each of the thin sheets having a thickness of 2 mm or less, each layer comprising secondary particles of calcium silicate crystals, a fibrous material, a coagulant and preferably additionally a polymer adsorbed on the surface of the secondary particles of calcium silicate; wherein each layer contains secondary calcium silicate particles interconnected with one another, and wherein the superposed thin sheets are firmly united with one another into an integral body by the interlayer interconnection of secondary particles of calcium silicate crystals present on the surface of the sheets.
