摘要
(US9469769) The anti-corrosion treatment composition for steel rebar embedded in concrete is a composition for coating steel rebar before the steel rebar is embedded in concrete.  The coating of the steel rebar with the anti-corrosion treatment composition forms a treatment film on the steel rebar which controls both uniform corrosion and pitting corrosion of the steel rebar after it has been embedded in the concrete.  The anti-corrosion treatment composition includes an inorganic acid, an organic acid, polyethylene glycol and water.  The inorganic acid forms between approximately 3.9 wt % and approximately 15.0 wt % of the anti-corrosion treatment composition, the organic acid forms between approximately 0.1 wt % and approximately 2.9 wt % of the anti-corrosion treatment composition, the polyethylene glycol forms between approximately 2.0 wt % and approximately 10.7 wt % of the anti-corrosion treatment composition, and the remainder of the anti-corrosion treatment composition is water.
