2. Description of the Related Art In recent years, research has been conducted in the construction field to utilize the abundant reserves of shirasu, but in the past, in most cases, secondary processing of this shirasu is used as a building material. There was no direct production of this shirasu in its original form without any processing.

[0003] That is, Shirasu is a common name of white sandy sediment, which is a general term for white rough eruptive volcanic products widely distributed in southern Kyushu and secondary sediments derived therefrom. Differentiation occurs, and the main components in the magma are SiO2, Al2O3, Fe2O3, FeO, MgO,
CaO, Na2O, K2O, etc. are gathered together and crystallized as minerals and exploded soon after explosion, and are formed by about 30% of crystalline minerals and about 70% of amorphous volcanic glass. In this amorphous volcanic glass, volatile components in the magma are rapidly released, forming a porous pumice,
65-73% of iO2, 12-16% of Al2O3, C
aO 2-4%, Na2O 3-4%, K2O 2-4%
And 1 to 3% of iron. The plagioclase is the most common crystalline mineral, and it contains a small amount of perovskite, quartz, ordinary pyroxene, and magnetite.
