25、hod used listed adjacent tothe reported data.1.1Recommended useThe information used to describe where the product should beused, any auxiliary or ancillary products, and acceptable serviceconditions are listed in this section. Examples: Horizontal,vertical, overhead, traffic wearing surface repairs,
26、 cosmetic.1.2Claimed benefitsAny benefits or special properties claimed for the productshould be listed in this section. Examples: Rapid strengthdevelopment, shrinkage compensated, polymer modified.1.3Stated limitationsAny stipulations or limitations placed upon the storage,mixing, use, application
27、methods, placement, curing, orexposure conditions should be listed in this section. Examples:Minimum/maximum placement depth with/without aggregate,application temperature range, moisture exposure, thermalcoefficient of expansion compared to substrate concrete,contains chlorides if content is high,
28、and special equipment,if any such is needed during application.CHAPTER 2DEFINITIONScementitious materialfor the purposes of this guide,cementitious material is defined as that fraction of the repairmaterial passing a No. 170 mesh (90 m) sieve per ASTME11, and mortar is defined as a material consisti
29、ng of acementitious binder with the only aggregate being fineaggregate, according to ASTM C33/C33M. No recognizedmethod could be found to physically separate the binder fromthe fine components of the repair material. Therefore anassumption is made that any material passing this size meshis to be con
30、sidered as binder or a cementitious component.Some of the following compositional reporting requirementsare based on the level of the component compared to thecementitious fraction, which is the purpose for determiningthe quantity of this size fraction of the repair material.concreteconcrete is eith
31、er a repair mortar that has beenextended with the addition of coarse aggregate or a concretemixture that was originally proportioned with coarse aggregate.Example: This repair mortar is composed of a precise blendof portland cement, microsilica, graded aggregates,redispersible polymer, and fine fibe
32、rs. Because differenttests for mortars and concretes are used for determination ofsome of the physical properties listed below, this definitionclarifies when the different test methods should be used.mortarmortar is a mixture of cement paste and fineaggregate, with or without additives.CHAPTER 3COMP
33、OSITION3.1Total sulfur trioxide (SO3) (ASTM C114)The total SO3content should be stated as a percentage bymass of cementitious constituents determined according toASTM C114. If sulfate levels are above those contributedfrom portland cement, the material producer should providedata and methods used to
34、 establish suitability for therecommended uses stated in Chapter 1.Gypsum or another calcium sulfate is added to portlandcement to prevent flash set. Test method ASTM C563 isgenerally used by cement manufacturers to determine theoptimum SO3content based on maximization of the 24-hourcompressive stre
35、ngth of a standard mortar mixture. Incement analysis, the convention is to report the chemicalconstituents at their highest oxidation state, which for sulfuris sulfur trioxide. Additions of sulfates beyond the optimumlevels determined by ASTM C563 or even beyond themaximum limits of ASTM C150 are so
36、metimes used toaccelerate the strength development or improve theshrinkage compensation of formulated products (Taylor1990). ASTM C845 defines three types of expansivecements, all of which would indicate elevated levels of sulfatein this analysis. Hewlett (2004) describes the expansive natureof diff
37、erent sulfates in contact with portland cement. Exposureto different sulfate solutions (either from outside environmentor leaching from internal additions) can cause what is commonlyknown as sulfate attack or an uncontrolled destructiveexpansion. Due to concern for potential over expansion orsuscept
38、ibility to deterioration in some environments, thetotal sulfur trioxide is to be reported as percentage by massof cementitious materials. Elsewhere in this document,sulfate resistance per ASTM C1012 is to be reported.3.2Total alkali content (ASTM C114)The total alkali content should be stated as a p
39、ercentage bymass of cementitious constituents determined as sodiumequivalent alkali according to ASTM C114.GUIDE FOR CEMENTITIOUS REPAIR MATERIAL DATA SHEET 364.3R-3The typical means by which the alkali content has beencontrolled with concrete mixtures in the U.S. has been toestablish a maximum limi
40、t only on the portland cement.Cement with an alkali content of less than 0.6%, expressedas equivalent Na2O, is referred to as low-alkali cement(ASTM C150). This provision proved satisfactory forconcrete. The disadvantage of establishing an alkali limitbased on the alkali of the portland cement alone
41、 for repairmaterials is that many proprietary repair materials containblends of different cements, additives, admixtures, and otherconstituents that contain alkali. It is the sum of the alkalisfrom all sources that is pertinent to the potential reactionwith a reactive aggregate.Past research conduct
42、ed in Germany and Canada led to theconclusion that when the alkali in a mixture is kept below amaximum of 5.0 lb/yd3(3.0 kg/m3), there will be no alkali-silica reaction (ASR) (Gress 1997).3.3Chloride contentThe total water-soluble (ASTM C1218/C1218M) andacid-soluble (ASTM C1152/C1152M) chloride cont
43、entsshould be stated as a percentage by mass of the mortar orconcrete, consistent with ASTM standards. The consider-ations of chloride-ion content discussed in ACI 222R shouldbe considered and may require a cautionary statement on thepackaging if an oxidizeable metal such as iron, steel, zinc, oralu
44、minum is allowed to be embedded in proximity of a chloridecontaining concrete repair material.BS 8110-1: 1997 and European Standard ENV 206-1:2004(CEN/TC 104), limit the total chloride ion content in reinforcedconcrete to 0.40% by mass of cementitious component. ACI318 considers water-soluble chlori
45、de ions only and sets arecommended limit of 0.15% by mass of cement(itious)component. The interaction of chloride levels with pH of themortar and oxygen availability in moist environments is respon-sible for many of the issues with reinforcing steel corrosion.3.4pHReport the pH of the fresh and hard
46、ened repair materialdetermined according to the following:Crush a hardened sample of the cementitious repair materialto pass a No. 170 (90 m) mesh sieve, stir 10 g of the crushedmaterial into 90 g distilled or deionized water for 1 minuteand, after settling, use pH paper or suitable pH meter per the
47、recommendations of the supplier of the pH equipment.Reporting of the pH of the freshly mixed material is usefulinformation for the applicator of the product. The pH of thehardened material is one indication of the degree ofpassivation that is imparted to embedded reinforcing steel.3.5Characteristics
48、 of aggregate(ASTM C33/C33M)Report the characteristics listed below according to ASTMC33/C33M and the following requirements:For prepackaged products, use the +170 mesh fractionobtained by wet sieving according to ASTM C117 forreporting the results of the tests specified in the section titled,“Metho
49、ds of Sampling and Testing” of ASTM C33/C33M.Fine aggregateGeneral characteristicsGradingDeleterious substancesSoundnessCoarse aggregateGeneral characteristicsGradingDeleterious substancesReporting the amount of fine and coarse aggregate, and thegradations of these components, provides useful informationto the applicator regarding selection of mixing and pumpingequipment.
