ICC-ES AC198 – Acceptance Criteria for Chemical Admixtures Used in Concrete
Scope
The ICC-ES Acceptance Criteria AC198 establishes guidelines for the evaluation of chemical admixtures used in concrete that have an impact on setting time. This includes:
- standard admixtures: those meeting existing code requirements for chemical admixtures.
- extended-set admixtures: those designed to significantly delay the setting time of concrete.
