SECTION 701 - HYDRAULIC CEMENT
701.01 General. The following requirements shall be applicable to hydraulic cement:
Only hydraulic cements conforming to Section 701 shall be used. Hydraulic cements shall not be listed or designated as meeting more than one AASHTO or Department type. Different brands of hydraulic cement, or the same brand of hydraulic cement from different mills, shall not be mixed or used alternately in any one class of construction or structure, without written permission from the Engineer; except that this requirement will not be applicable to hydraulic cement treatment of design soils, or bases. The Contractor shall provide suitable means for storing and protecting the hydraulic cement against dampness. Hydraulic cement that has, for any reason, become partially set or that contains lumps of caked hydraulic cement will be rejected. Hydraulic cement salvaged from discarded or used bags shall not be used. The temperature of bulk hydraulic cement shall not be great er than 165°F at the time of incorporation in the mix. Acceptance of hydraulic cement will be based on the certification program as described in the Department’s Materials Division Inspection, Testing, and Certification Manual and job control sampling and testing as established by Department SOP. Retests of hydraulic cement may be made for soundness and expansion within 28 days of test failure and, if the hydraulic cement passes, it may be accepted. Hydraulic cement shall not be rejected due to failure to meet the fineness requirements if, upon retests after drying at 212°F for one hour, it meets such requirements.
701.02 Portland Cement.
701.02.1 General.
701.02.1 1--Types of Portland Cement. Portland cement shall be either Type I or Type
II conforming to AASHTO M85. Type III cement conforming to AASHTO M85 or Type III (MS), as defined by the description below in Table 1, may be used for the production of precast or precast-prestressed concrete members.
701.02.1 2--Alkali Content. All cement types in this Subsection shall meet the Equivalent
alkali content requirement for low-alkali cements listed in AASHTO M85, Table 2.
701.02.2 Replacement by Other Cementitious Materials. The allowable replacement
of cement by weight is 20-25% for fly ash or 45-50% for ground granulated blast furnace slag (GGBFS). Replacement contents below the minimum tolerance of fly ash or GGBFS may be used, but shall not be given any special considerations, such as the maximum acceptance temperature for portland cement conc rete containing pozzolans in Subsection
804.02.13 1.5. Special considerations shall only appl y for replacement of cement by fly
ash or GGBFS.
701.02.2 1--Portland Cement Concrete Exposed to Soluble Sulfate Conditions or
Seawater. When portland cement concrete is exposed to moderate or severe soluble sulfate conditions, or to seawater, cement types and replacement of cement by Class F fly ash, GGBFS, or silica fume shall be as follows in Table 1. Table 1- Cementitious Materials for Soluble Sulfate Conditions or Seawater Sulfate Exposure Water-soluble sulfate (SO
4.in soil, % by mass Sulfate (SO4) in water, ppm Cementitious material required Moderate and Seawater 0.10 - 0.20 150 - 1,500 Type II * cement, or Type I cement with one of the following replacements of cement by weight: 24.5-25% Class F fly ash,or 49.5-50% GGBFS Severe 0.20 - 2.00 1,500 - 10,000 Type I cement with a replacement by weight of 49.5- 50% GGBFS, or Type II cement with one of the following replacements of cement by weight: 24.5-25% Class F fly ash, 49.5-50% GGBFS * Type III cement conforming to AASHTO M85 with a maximum 8% tricalcium aluminate (C3A) may be used in lieu of Type II cement as allowed in Subsection
701.02 1; this cement is given the designation “Type III(MS).”
Class C fly ash shall not be used as a replacement for cement in any of the sulfate exposure conditions listed above.
701.02.2 2--Hydraulic Cement for Soil Stabilization Exposed to Soluble Sulfate
Conditions or Seawater. When hydraulic cement for use in soil stabilization is exposed to moderate or severe soluble sulfate c onditions, or to seawater, cement types and replacement of cement by Class F fly ash or GGBFS shall meet th e requirements of Subsection 701.02.2.1. Silica fume shall not be used to bring the cementitious materials into compliance with the requirements of Table 1.
701.03 Masonry Cement. Masonry cement shall conform to ASTM C 91 and shall only
be used in masonry applications.
701.04 Blended Hydraulic Cement.
701.04.1 General.
701.04.1 1--Types of Blended Cement. Blended hydraulic cements shall be of the
following types and conform to AASHTO M 240: Type IS – Portland blast-furnace slag cement Type IP – Portland-pozzolan cement Type IL – Portland-limestone cement Blended cement Types IS, IP, and IL for use in hydraulic cement concrete or soil stabilization exposed to the moderate soluble sulfate condition or exposure to seawater as defined in Table 2 shall meet the sulfate resistance requirement listed in AASHTO M 240, Table 4 and the “(MS)” suffix shall be added to the type designation. Type IL cement may be used for soil cement stabilization.
701.04.1 2--Alkali Content. All blended hydraulic cement shall be made with clinker that
would result in cement meeting the requirements of Subsection 701.02.1.2 when used in the production of AASHTO M 85, Type I or Type II cement.
701.04.2 Replacement by Other Cementitious Materials. The allowable replacement
of blended cement Type IL by weight is 35% for fly ash or 45-50% for GGBFS. Replacement contents below 20% for fly ash or 45% for GGBFS may be used, but shall not be given any special considerations, such as the maximum acceptance temperature for blended hydraulic cement concrete containing pozzolans in Subsection 804.02.13.1.5. Special considerations shall only apply for replacement of blended cement by fly ash or GGBFS. No additional cementitious materials, such as hydraulic cement, blended hydraulic cement, fly as h, GGBFS, or others, shall be added to or as a replacement for blended cement Types IS and IP.
701.04.2 1--Blended Hydr aulic Cement Concrete Exposed to Soluble Sulfate
Conditions or Seawater . When blended hydraulic cement concrete is exposed to moderate or severe soluble sulfate conditions, or to seawater, cement types and
