Since it is impossible to reconstruct the top level that has collapsed, a formwork is constructed to squeegee mortar or spray mortar, and repair kits are being used in Korea to chip away the damaged concrete of the bridge deck structure.In Korea, a jolly rancher filled gummies technique called hydro-demolition replaces water blasting and water jetting by using high-pressure water to remove not only asphalt but also old and broken concrete.Additionally, dry materials including cement, aggregate, and additives are carried via the inside of a hose to the field using compressed air, where they meet water and are ejected at a high rate of speed.This technique is known as dry mix shotcrete.Using the gel bottle audrey the devised automatic hydraulic dismantling technology and high-performance dry-mix shotcrete, field application results are discussed in this study.
