Use of Hydrodemolition to Remove Deteriorated Concrete from Bridge Decks
Hydrodemolition is a relatively new method of removing select portions of a hardened concrete structure. By utilizing the erosive power of high-velocity water streams, hydrodemolition equipment breaks up concrete by disintegrating the cement matrix between aggregates. The demolishing effect can be tightly controlled to a desired level of removal, ranging from light scarification of the surface to deep penetration of the structural element. The use of the hydrodemolition process has several advantage over conventional concrete removal methods, such as jackhammering. These advantages include: reduction in new damage caused by the removal process; automation, which produces a very consistent level of removal energy over large areas; the ability to seek out and removal weak or deteriorated location at various depths; and, a rough, high-quality bonding surface for repair materials. These characteristics are favorable for construction projects that involve rehabilitation of corrosion-damaged, reinforced concrete structures, particularly bridge decks.
