1. Rationale
1. To adopt cleaner wording for aggregates in C 1622.
2. To create a Type H, Harmless, Special Performance Admixture, category for admixtures that are not covered by the existing types in the standard. The Type H category is to ensure that such admixtures do not adversely impact the fresh, hardened and durability properties of concrete.
