This lime is used with pozzolans. The lime shall conform to the required physical and chemical limits: chemical factor, blaine fineness, and pozzolanic receptivity index. The following test methods shall be done: determination of calcium oxide, magnesium oxide, and carbon dioxide; calculation of chemical factor; blaine fineness; pozzolanic receptivity index; lime-pozzolan strength; and lime-pozzolan-aggregate strength and freeze-thaw resistance.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 1.
