This standard has been approved for use by agencies of the Department of Defense. NOTE 1Finely divided materials may tend to reduce the entrained air content of concrete. Hence, if a y ash or natural pozzolan is added to any concrete for which entrainment of air is specied, provision should be made to ensure that the specied air content is maintained by air content tests and by use of additional air-entraining admixture or use of an air-entraining admixture in combination with air-entraining hydraulic cement.

NOTE 2This denition of y ash does not include, among other things, the residue resulting from: 1 the burning of municipal garbage or any other refuse with coal; 2 the injection of lime directly into the boiler for sulfur removal; or 3 the burning of industrial or municipal garbage in incinerators commonly known as incinerator ash.


Classication 4. This class of y ash has pozzolanic properties. This class of y ash, in addition to having pozzolanic properties, also has some cementitious properties. NOTE 3Class F y ash is typically produced from burning anthracite or bituminous coal, but may also be produced from subbituminous coal and from lignite.

Class C y ash is typically produced from burning lignite or subbituminous coal, and may also be produced from anthracite or bituminous coal. Class C y ashes typically have total calcium contents, expressed as calcium oxide CaO , that are higher than Class F y ashes.

No other units of measurement are included in this standard.This class of y ash has pozzolanic properties.

Historical Version s - view previous versions of standard. Class C y ashes typically have total calcium contents, expressed as calcium oxide CaO , that are higher than Class F y ashes.
