NOTE: EPA recommends that procuring agencies use
flowable fill containing coal fly ash (pozzolan)
and/or ferrous foundry sands for backfill and other
fill applications. EPA further recommends that
procuring agencies include provisions in all
construction contracts involving backfill or other
fill applications, to allow for the use of flowable
fill containing coal fly ash and/or ferrous foundry
sands, where appropriate.
Include the limits on soluble alkalies for portland
cement and for pozzolan whenever there is a
possibility of alkali-aggregate reactive aggregates
being furnished.
Where alkali-bearing soil or groundwater is
encountered, or where the concrete will be exposed
to seawater, brackish water, or sewage, see ACI
201.2 R for guidance on selecting cementitious
material. See EM 1110-2-2000 for guidance when
proposing to use any type of portland-pozzolan or
portland-furnace-slag cement.
Edit bracketed items as required.
**************************************************************************
Cementitious Materials shall be portland cement, [portland-pozzolan
cement,] [portland blast-furnace slag cement,] or portland cement in
combination with [pozzolan] [or ground granulated blast furnace slag] [or
silica fume] and shall conform to appropriate specifications listed below.
Use of cementitious materials in concrete which will have surfaces exposed
in the completed structure shall be restricted so there is no change in
color, source, or type of cementitious material.
2.1.1
Portland Cement
ASTM C 150, Type I [low alkali] with a maximum 15 percent amount of
tricalcium aluminate, or Type II [low alkali] [including false set
requirements] or [Type V]. White portland cement shall meet the above
requirements except that it may be Type I, Type II or Type III [low
alkali]. White Type III shall be used only in specific areas of the
structure, when approved in writing.
2.1.2
High-Early-Strength Portland Cement
ASTM C 150, Type III with tricalcium aluminate limited to [5] [8] percent,
[low alkali]. Type III cement shall be used only in isolated instances and
only when approved in writing.
2.1.3
Blended Cements
**************************************************************************
NOTE: Never specify I(PM) or I(SM) cement.
