It is increasingly clear that steps must be taken to enhance the durability of concrete structures. Engineers today are designing new structures expected to last over a century, while owners of existing structures that are reaching the end of their designed service life are looking for ways to maintain them for further use. Corrosion of metal reinforcement is a critical risk factor for durability of structures, and as such, the development and selection of corrosion inhibiting admixtures is a consideration to take seriously. Cortec® Laboratories can assist stakeholders in the all-important screening process by performing accredited testing to ensure admixtures measure up to widely accepted industry standards for the selection and qualification of corrosion inhibiting admixtures. One such test is G180, a corrosion inhibition test measurement option under ASTM C1582, Standard Specification for Admixtures to Inhibit Chloride-Induced Corrosion of Reinforcing Steel in Concrete.
