حماية حديد التسليح المغمور في المحلول الإلكتروليتي من التآكل باستخدام المثبطات

الملخص EN

Corrosion of steel reinforcement is one of the biggest problems facing all countries in the world like bridges in the beach area and marine constructions which lead to study this problems and apply some economical solution .According to the high cost of repair for these constructions, were studied the effect of using sodium phosphate and sodium silicate as corrosion inhibitors admixture for steel bars that submerged partially in electrolyte solution (water + sodium chloride in 3 % conc.).

The two inhibitors above added to the electrolyte solution in dosages (2 %, 3 % and 4 %) for both of them.

The results were : corrosion rate for steel sample that's submerged partially in only water solution was lower than corrosion rate of steel bar that's submerged partially in electrolyte solution Also the two corrosion inhibitors (sodium phosphate and sodium silicate) that added to the electrolyte solution were working successfully to prevent and inhibit the corrosion by using weight loss technique with best dosage of 4 % sodium phosphate (efficiency 94 %) and best dosage of 2 % sodium silicate (efficiency 93 %).
