Research on Chloride Appropriate Dosage for Incorporated Accelerated Corrosion

Abstract:

Mixing chlorine is one of the ways to ensure the theory and practical steel bars corrosion rate closer when mixing concrete for laboratory electrochemical accelerated corrosion and appropriate chloride dosage should guarantee the steel bars are in the critical corrosion state when we start to accelerated corrosion. By comparing the specimens’ experimental compressive strength, chloride-permeation resistance, corrosion potential measured by the half-cell potential method and polarization potential curves measured by the linear polarization potential method with different Nacl dosage, we get the appropriate Nacl dosage is nearly 1.90%, namely cl^- content is about 1.15%.
