ものを用いるのが好ましい。Calcium hydroxide and silica-based mineral particles are added in order to obtain sufficient strength by the reaction of Ca (OH) 2 with SiO 2 in the mineral. As calcium hydroxide, plaster is used. It is practical to use. Further, as the silica-based mineral particles, silica sand, fly ash, slag, shirasu, silica fume, diatomaceous earth,
Activated clay and the like can be mentioned. Of these, silica sand is particularly preferable. When silica-based mineral particles such as silica sand are coarse particles having a large particle diameter, the unfired tile obtained has a good appearance and is rich in naturalness.
The reactivity with (OH) 2 becomes low, and the strength may be insufficient. Conversely, if the particle size is small, Ca (O
H) 2 has good reactivity and the resulting unfired tile has high strength, but on the other hand, it is slightly inferior in design. Therefore, it is preferable to use silica-based mineral particles having a particle size of about 1 to 5 mm.
