97) is a method of stopping water leakage from concrete cracks, etc., and because it is a method limited to local areas, there is a large disparity between the inside and outside of large-scale ground improvement and water stopping of underground structures, resulting in problems with overall strength, shrinkage, and pollution. The problem arises.

内で発泡性コンクリートを凝固せしめた。This is an innovative construction method that exerts sufficient force on structures and works uniformly (Example) Silica sand 200 is a mixture of 100 parts by weight of alumina cement or Portland cement with carbon or alkali-resistant short glass fibers. One-component Eiwa reaction type urethane resin (Hicel OH manufactured by Toho Chemical Industry Co., Ltd.) is used when pouring cement slag, which is a mixture of 5 parts by weight of aluminum or aluminum alloy fine powder and 1.00 parts by weight of fresh water. 50 parts by weight of injection urethane resin were mixed at the tip of an injection gun and simultaneously injected to solidify foamable concrete in soft ground.
養生期間を経て従来の数倍の強度と耐久性があることを
確認した。After a curing period, it was confirmed that the material was several times stronger and more durable than conventional products.
