Abstract:
As one potential solution to the ever-present problem of corrosion deterioration of reinforced concrete structures, corrosion-inhibiting admixtures have been researched and introduced into service. The objective of this phase of study was to determine the influence of a series of commercially available corrosion-inhibiting admixtures on general concrete handling, performance, and durability properties not related to corrosion inhibition. The concrete properties tested include air content, slump, heat of hydration, compressive strength, chloride diffusion, and electrical indication of chloride permeability. The performance of each specific admixture is discussed, relative to the inter-relationships between observed test results.
