The Allowable Admixed Chloride Conundrum
The American Concrete Institute (ACI) is widely recognized as a leading developer and distributor of consensus-based standards, technical resources, and certification/educational programs for those involved in concrete design, construction, and materials. Concrete is generally a durable material. Nevertheless, corrosion of steel reinforcement is a recurring and festering issue within the industry. The amount of chlorides included in new concrete can influence the service life of a structure. The current documents published by ACI committees provide no clear guidance on what the C^sub A^ limit should be in concrete. In fact, 12 ACI documents have five different requirements for C^sub A^. Therefore, these limits are confusing to the user and could result in increased risks to the concrete producer, contractor, and/or owner, depending on the CA limit used. An ACI-initiated task group could focus on resolving this C^sub A^ limits conundrum. Although significant research is needed to develop information for setting these C^sub A^ limits in concrete, sufficient information is available to generate a more unified approach within ACI documents.
