Corrosion Control with Protectosil® CIT and Protectosil® DRY CIT

Protectosil® CIT prevents corrosion

WJE Associates 1) carried out tests on steel-reinforced concrete slabs in accordance with methods of the US federal highway administration. Some of the slabs were coated with about 600g/m2 of Protectosil® CIT, whereas other specimens were exposed to a cyclic saltwater (15wt% NaCl solution) ponding test without any protection. Corrosion current, the resistance and halfcell potentials were measured. The ponding test of an unprotected specimen showed active corrosion after 250 days (see graph below), which is indicated by a very high macrocell corrosion

current. The formerly unprotected specimens were dried after the 250 day test and Protectosil® CIT was applied. After one week of curing the ponding test was continued. By using Protectosil® CIT, the corrosion current in the formerly unprotected specimen decreased by 90%.

 

Protectosil® CIT decreases effectively the corrosion current by 90 %.
