Fosroc Auramix BCI — Corrosion Inhibitor Admixture for Reinforced Concrete | Fosroc India (240 kg)

Corrosion doesn't announce itself. By the time spalling concrete and rust stains appear on a structure's surface, the steel reinforcement inside has already been compromised for years — and what started as a preventable chemical process has become a repair bill that far exceeds what protection would have cost. Fosroc Auramix BCI is the corrosion inhibitor admixture from Fosroc Chemicals India that stops that process at the source — mixed into fresh concrete during batching to protect embedded steel reinforcement from the chloride-induced corrosion that is the primary cause of premature structural deterioration in aggressive environments.

As part of Fosroc's Auramix admixture range — the same family as their polycarboxylate superplasticizers — BCI integrates cleanly into complete Fosroc-specified concrete mix designs. If you're already working with Auramix superplasticizers for workability management, adding BCI to the same mix for corrosion protection is a single-supplier, technically compatible decision that simplifies specification without any compromise on performance. The inhibitor works by disrupting the electrochemical corrosion mechanism at the steel surface — forming a protective molecular film that prevents chloride ions from initiating the corrosion reaction even as they accumulate in the concrete over time.

For coastal structures, marine infrastructure, industrial buildings in polluted environments, and any reinforced concrete in aggressive ground or water conditions — specifying Auramix BCI in the original mix design is one of the most cost-effective durability investments available in the construction chemical market. The cost of the admixture in the mix is a fraction of what chloride-induced corrosion repair costs once the structure deteriorates. Backed by Fosroc's globally trusted expertise.
