1、Designation: D5370 14Standard Specification forPozzolanic Blended Materials in Construction Applications1This standard is issued under the fixed designation D5370; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last re
2、vision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers pozzolanic blended materialfor use in construction applications where the propertiesnormally attrib
3、uted to coal fly ash and raw or calcinedpozzolans, like silica fume, and slag cement.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns, if any, associate

16、NOTE 2Certain raw materials like fly ash and cement kiln dust, whichblends are covered by this specification, vary from source to source, aswell as within sources.7. Blended Pozzolan for Use with Lime47.1 Ensure that blended pozzolan conforms to the require-ments prescribed in Specification C593.8.
17、Blended Pozzolan for Use in Concrete58.1 Ensure that blended pozzolan conforms to the chemicaland physical requirements as prescribed in the tables ofSpecification C618. The purchaser will specify the mineraladmixture class (in Specification C618). Carbon may substitutefor loss on ignition requireme
