Concrete Admixtures - ASTM Categories

ASTM C494 specifies the requirements for seven chemical admixture types. They are:

• Type A: Water-reducing admixtures
• Type B: Retarding admixtures
• Type C: Accelerating admixtures
• Type D: Water-reducing and retarding admixtures
• Type E: Water-reducing and accelerating admixtures
• Type F: Water-reducing, high range admixtures
• Type G: Water-reducing, high range, and retarding admixtures

Note: Changes occur in the admixture industry faster than the ASTM consensus process. Shrinkage Reducing Admixtures (SRA) and Mid-Range Water Reducers (MRWD) are two areas for which no ASTM C494-98 specifications currently exist.
