Proposals for stricter limits on chlorides added to concrete mixes are being made. This article is comprised of a list of arguments from various sources dealing with the general idea of tighter limits, not the exact level at which limits ought to be set. Example:
FAVORING STRICTER LIMITS: If chloride from the environment intrudes concrete, any calcium chloride that has been intentionally added to the mix will augment the action of the intruded chloride in promoting corrosion.
OPPOSED TO STRICTER LIMITS: Evidence that calcium chloride and admixtures containing calcium chloride have contributed seriously to corrosion is scarce. Many times, however, corrosion caused by penetration of chloride deicers into concrete has been wrongly attributed to calcium chloride introduced as an admixture.
