生じるという問題点があった。By the way, conventionally, a solidifying material is added to muddy water made of viscous soil and water, and air bubbles are added to the muddy water with stirring to produce lightweight soil for civil engineering work. When stirring and mixing the solidified material and air bubbles, air is entrained and large air bubbles are mixed into the lightweight soil, making it difficult to control the quality of the lightweight soil. Large bubbles that float up,
There has been a problem that the materials are separated, the strength and density are reduced, and water pollution is also caused.
