A ADMIXTURE COMPOSITE FOR CABE TROUGH CONCRETE WITH INDUCTION PROPERTY OF ELECTRICAL CURRENT

摘要

PURPOSE: An additive composition with the current induction characteristic for cable through concrete is provided to reduce the electromagnetic induction phenomenon of an internal cable and protecting a through cable by mixing inorganic fiber and metal fiber-phase materials in a through main body. CONSTITUTION: An additive composition includes inorganic fiber-phase materials, single or composite fiber of steel fiber or carbon fiber, an argillaceous reinforcing agent, and a hydroxide additive. The argillaceous reinforcing agent is one or two or more selected from sodium bentonite, calcium bentonite, and montmorillonite. The hydroxide additive is one or two or more selected from magnesium hydroxide, calcium hydroxide, and aluminum hydroxide.
