Title:
コンクリートパッチ修復における犠牲アノード
Document Type and Number:
Japanese Patent JP2012505985
Kind Code:
A
Abstract:
High performance proprietary cementitious concretes or mortars developed for use as patch repair materials for corrosion damaged concrete often have high resistivities that inhibit the performance of sacrificial anodes located within the patch repair areas. A method of repair is disclosed which comprises removing the corrosion damaged concrete to form a cavity 2 to receive a concrete repair material. Within this cavity 2 a smaller distinct cavity for assembling a sacrificial anode assembly and placing within this second cavity a pliable viscous ionically conductive backfill, a sacrificial anode and an activating agent to form a sacrificial anode assembly 5. This assembly 5 is connected to the steel 6. The anode and the backfill in the second cavity are covered with a repair material to restore the profile of the concrete structure. In this arrangement a high resistivity repair material promotes the flow of protection current to steel in adjacent contaminated concrete that is at risk of corrosion. The backfill may comprise a lime putty.
