It is well documented that the amount of chlorides included in new concrete can influence the service life of a structure. While many ACI documents therefore provide limits on the maximum allowable amount of admixed chlorides, the limits are not consistent among those documents. The various limits may be leading to higher risks and costs for contractors and/or owners. The authors call for ACI committees to discuss this conundrum and suggest the creation of an ACI-initiated task group to resolve it.
