Cementitious Materials
1.6.1.1
Transportation
When bulk cement, pozzolan, dry silica fume, or ground granulated
blast-furnace slag is not unloaded from primary carriers directly into
weather-tight hoppers at the batching plant, transportation from the
railhead, mill, or intermediate storage to the batching plant shall be
accomplished in adequately designed weather-tight trucks, conveyors, or
other means that will protect the material from exposure to moisture.
Transportation facilities for dry bulk silica fume shall be approved in
advance.
1.6.1.2
Storage
Cementitious materials shall be furnished in bulk except that cement used

cementitious materials, shall be stored in separate dry, weather-tight, and
properly ventilated structures. All storage facilities shall permit easy

that has been stored at the site for 60 days or more before using cement of
lesser age. Silica fume in slurry form that has been in storage at the
project site for longer than recommended by the manufacturer or that has
been subjected to freezing shall not be used in the work and shall be
