If the modification is made mainly of OMg0.2SiO, the melting point and viscosity will be lowered, the water slag ratio will be improved, and it will become mainly glass. After drying, it will be crushed and a small amount of alkaline irritants (e.g. CaO, Ca (OH), cement, etc.) will be added. It has been found that when kneaded with water, it has hydraulic properties, and silicate rocks, minerals, etc. are added to uniformize the development of sludge solidification strength.
