c.
The maximum mass of fly ash, natural pozzolans, ground granulated
blast-furnace slag, or silica fume that is included in the
calculation of water-to-cementitious materials ratio shall not
exceed the following limits:
(1) Fly ash shall not be used for more than 25 percent by mass of
the cementitious material. The fly ash and other pozzolans
present in a Type IP or IPM blended cement, ASTM C 59/C 59M5M ASTM
C 59/C 59M5, shall be included in the calculated percentage. If
fly ash or other pozzolan is used in concrete with slag, the
portland cement shall not be less than 50 percent of the total
mass of cementitious materials. A higher percentage of fly ash
may be used if tests are made using actual job materials to
ascertain the early and later age strengths and durability
