Plack New Wording of Clause B.2.1.3 – Class L B.2.1.3Class L Class L composite well cement is obtained by intergrinding Portland cement clinker and one or more forms of calcium sulfate with fly ash as specified in B.2.2.3, or with other pozzolanic material as specified in B.2.2.2, or by blending separately produced Portland cement with separately processed fly ash as specified in B.2.2.3, or with other pozzolanic material as specified in B.2.2.2. At the manufacturer’s discretion, other materials may be used for modifying performance characteristics, provided such additives do not prevent the composite well cement from performing its intended functions. This product is intended for use under conditions when a lower density cement slurry is desired.
