Document Type and Number:
Japanese Patent JPH06100991
Kind Code:
A
Abstract:
PURPOSE: To obtain a seawater corrosion resisting reinforcing bar which is used for a concrete structure set at the seaside area, a concrete structure set in the ocean, and a reinforced concrete structure, a concrete bridge, etc., exposed to sea salt grains and seawater splashes and is remarkably excellent in its degradation preventing action.
