17、ul history of performance in the same or similarexposures.NOTE 1Since all conditions of use cannot be anticipated, thisspecification requires nonshrink grout to exhibit no shrinkage when testedin a laboratory-controlled, moist-cured environment, and requires only thereporting of the observed height

18、change, usually shrinkage, when testspecimens are subjected to some degree of drying. It is suggested thatusers consult with manufacturers on specific applications to determine theapplicability of specific test results.5. Materials5.1 The materials used as ingredients in packaged, dry,grout include

19、hydraulic cement, fine aggregate, and otheringredients.6. Performance Requirements6.1 All test specimens for performance evaluation shall beprepared using the highest water-to-solids ratio, maximumflow, or most fluid consistency stated on the package.6.2 Specimens shall be made at 23.0 6 2.0C 73.5 6

20、3.5F from freshly mixed grout and from grout that has beenretained in the mixer for the maximum usable working timeallowed by the manufacturer. The results of tests performed onspecimens made from both conditions shall meet the require-ments prescribed in Table 1.6.3 Additional specimens shall be pr

21、epared from freshlymixed grout and from grout that has been retained in the mixerfor the maximum usable working time allowed by the manu-facturer using materials and equipment conditioned to tempera-tures representing the maximum and minimum usable tempera-tures specified by the manufacturer. The re

22、sults of testsperformed on specimens stored at the temperature extremesshall meet the requirements prescribed in Table 1, except thatthe compressive-strength requirements do not have to be met atminimum usable temperature.6.4 Specimens for testing shall be stored continuously at thethree required te

23、mperatures (23.0 6 2.0C 73.5 6 3.5F,maximum usable temperature specified by the manufacturer,and minimum usable temperature specified by the manufac-turer).7. Sampling7.1 Use whole packages of grout selected at random fromthe lot of grout to be examined.7.2 Where lesser quantities of grout will serv

24、e the purpose,select 3000 g 7 lb of dry grout from a whole package inaccordance with the mechanical-splitter method in PracticeC702. For high-density grouts, adjust the mass to provide anequivalent volume.8. Batching8.1 Grout mixtures shall be produced in the followingconditions:8.1.1 Batch grout mi

25、xtures at temperature conditions corre-sponding to the maximum recommended temperature limit andat a temperature corresponding to the minimum temperaturestated by the manufacturer.8.1.2 For standard temperature testing, maintain the groutmixture and the testing equipment at a temperature of 23 62C 7

26、3.5 6 3.5F.8.2 Bring all materials and equipment to be used in prepar-ing test specimens to the specified test temperature, 63C65F prior to use.8.2.1 When the controlled-environment test room is toosmall to accommodate large equipment, immediately prior touse, bring the mixer to the desired testing

27、temperature by fillingit with water at the appropriate temperature and agitating it byturning the mixer on. When this water has stabilized at thedesired temperature, discard it and start preparing the batchimmediately.8.3 The manufacturer is not prohibited from including, inthe package instructions,

28、 procedures for adjusting the mixingwater temperature to achieve limitations imposed on the groutuse temperatures. Use of this technique shall not abrogate theextended mixing time requirement of this specification.9. Proportioning9.1 The minimum and maximum amount of water recom-mended by the manufa

29、cturer on the package shall be used todetermine conformance with the requirements of this specifi-cation. If the manufacturer provides maximum flow (thinnestconsistency) information on the package, conduct consistencytests to an accuracy of 65 % to determine the amount of waterto be added for testin

30、g. In either case, express the weight ofwater so determined as a ratio of water to dry grout material byweight. If both are given, make tests at whichever involves thelarger amount of water by ratio of dry grout mixture.10. Mixing10.1 Either the mixer described in Practice C305 or themortar mixer de

31、scribed in 10.1.2 shall be used for performancequalifications. In the event of a dispute, the mixer described in10.1.2 shall be used for the referee test.NOTE 2The referee test is a test made to settle disagreement as to theconformance to the specified requirements.10.1.1 Bench Scale Epicyclic Mixer

34、acityhorizontal shaft stationary drum mortar mixer (see Note 3)isrequired. The mortar mixer shall have a metal shell withhorizontal mixing blades. The mixing blades shall be angled sothat adjacent paddle arms reverse the flow of the grout in themixing drum during rotation of the horizontal shaft. Th

35、emixing blades shall have adjustable wiper blades that wipe theinner surfaces of the mixing chamber. The wiper blades shallbe rubber or other flexible, wear-resistant material that does notdeleteriously react with the grout mixture. The wiper bladesshall be adjusted to continuously wipe the curved i

36、nner surfaceof the mixing chamber below the grout level and the ends ofthe chamber. The horizontal shaft shall rotate the mixingpaddles at 28 to 35 r/min. The mixer shall be clean, pre-wetted,and drained and essentially free of hardened mortar and otherforeign material that can be removed with a tro

37、wel or byreasonably striking with a hammer.NOTE 3An electric motor-driven mixer is preferable in the laboratoryto avoid noise and exhaust fumes. For greater safety, the mixer should beequipped with a lever-operated clutch. While these comments are selectedsafety precautions, it is the users responsi

38、bility to see that any equipmentin use is not hazardous in a physical or mechanical way to operators andattendant personnel, and that safe work practices are required at all times.10.2 Mixing Procedure for Bench Scale Mixing:10.2.1 Use a 3000-g 7-lb sample to determine the consis-tency classificatio

39、n and to determine the water content of grouttested at maximum flow or most fluid consistency.10.2.2 Weigh all grout on a balance or on a platform scale tothe nearest 0.1 %.10.2.3 Measure the water by mass or volume to the nearest0.1 %. If the manufacturer recommends maximum watercontent, calculate

40、the percent water from the packaging infor-mation and use that amount of water to prepare the groutmixture. If the manufacturer recommends maximum flow ormost fluid consistency, use the suggested water content as astarting point and adjust water as necessary to achieve themaximum flow or most fluid

41、consistency stated on the package.If the required consistency has not been met, make additionaladjustments to estimate the water content to use for the nextbatch. Discard current batch and repeat with newly establishedwater content.10.2.4 Place water in the bowl. Start the mixer at speed 1.Add the d

42、ry grout material to the water over approximately 30sec. After 1 min, stop the mixer for 15 sec and scrape into thebatch any grout that may have collected on the side of thebowl. Switch to speed 2 and mix for a total of 5 min asmeasured from first contact of dry material with water. Useother mixing

43、procedures if recommended by the manufacturer.NOTE 4It is advisable to cover the bowl with a lid while mixing. Ametal disc in which a slit has been cut to accommodate the mixer shaft hasbeen found suitable. If excessive splash-over occurs, a larger mixer shouldbe used.10.2.5 Prepare required specime

44、ns from additional batchesof grout as needed. Use the water content established above forall successive batches. When testing grout at the end of itsworking time, a separate batch of grout shall be mixedcontinually until the time of test unless otherwise recom-mended by the manufacturer.10.3 Procedu

45、re for Using The Mortar Mixer:10.3.1 Prepare all specimens from a single batch of groutusing the horizontal shaft stationary drum mortar mixer.Perform tests to verify compliance with performance require-ments.10.3.2 With materials and equipment brought to the testingtemperature, use enough whole bag

46、s of material to produce atleast 56 L 2 ft3 of mixed grout. Use this batch for bothfreshly-mixed and delayed-mixed testing at one specifiedtemperature. Place the total required amount of mixing water inthe mixer (see Note 5).10.3.2.1 When testing a grout to a maximum water to solidsratio, use the we

47、ighed contents of the packages to determinethe amount of water to be used.10.3.2.2 When testing a grout to a maximum recommendedflow or most fluid consistency, adjust the water content at thetime of mixing to achieve the recommended consistency. Withthe mixer running, add the grout material to the w

48、ater in asteady flow, sliding it into the mixer along the side away fromthe discharge. After mixing for 1 min, stop the mixer for notmore than 30 s and scrape down the sides and blades. Mix foran additional 5 min after all the dry material has been added,unless otherwise recommended by the manufactu

49、rer. If therequired consistency has not been met, make additional adjust-ments to estimate the water content to use for the next batch.Discard current batch and repeat with newly established watercontent.NOTE 5Extensive lumping generally occurs during the procedure foradding grout to water. If it occurs repeatedly, try adding about 80 % of thewater, then add all of the dry grout material.Add the remaining water afterabout 1 min of mixing. If lumping persists, contact the grout manufacturerfor recommendations.10.3.3 After completely
