Pozzolans (such as coal fly ash, raw,or calcined natural pozzolans) react with lime in the presence ofmoisture. Hydrated lime and lime putty react with carbon dioxide fromthe air. Groun

C 1384C1180072SUMMARY OF CHANGESCommittee C12 has identified the location of selected changes to this standard since the last issue(C 1180 03ae1) that may impact the use of this standard. (Approved July 1, 2007.)(1) Added water retention and water
31、retentivity as new terms.(2) Added introductory language in 3.1, and added Terminolo-gies C43, C 1209, and C 1232 to Section 2.(3) Added Practice C 946, Test Method C 1324, Test MethodC 1403, and Guide C 1586 to Sections 1.2 and 2.This standard is subject to revision at any time by the responsible t
