17、 information tothe manufacturer and obtain assurance that the grout has asuccessful history of performance in the same or similarexposures.NOTE 1Since all conditions of use cannot be anticipated, this speci-fication requires nonshrink grout to exhibit no shrinkage when tested in alaboratory-controll

18、ed, moist-cured environment, and requires only thereporting of the observed height 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 result

19、s.5. Materials5.1 The materials used as ingredients in packaged, dry,grout include hydraulic cement, fine aggregate, and otheringredients.6. Performance Requirements6.1 Specimens shall be made from freshly mixed grout andfrom grout that has been retained in the mixer for the maximumusable working ti

20、me allowed by the manufacturer. Specimensfrom both conditions shall meet the requirements prescribed inTable 1.6.2 Specimens shall be prepared using materials and equip-ment at temperatures representing the maximum and minimumusable temperatures specified by the manufacturer for hisproduct. Specimen

21、s from both conditions shall meet therequirements prescribed in Table 1, except that thecompressive-strength requirements do not have to be met atminimum usable temperature.6.3 Specimens for testing shall be prepared by combiningthe use of grout retained in the mixer as in 6.1 with theminimum and ma

22、ximum as mixed and curing temperaturesused in 6.2. Specimens from these combinations of conditionsshall meet the requirements of Table 1, except that thecompressive-strength requirements do not have to be met atminimum usable temperature.6.4 All test specimens for performance evaluation shall beprep

23、ared using the highest water to solids ratio, maximum flow,or most fluid consistency stated on the package.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 serve the purpose,select 3000 g 7 lb of dry grout fro

24、m a whole package inaccordance with the mechanical-splitter method in PracticeC 702. 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 mixtures at temperature conditions corre-sponding

25、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 6 2C 73.5 6 3.5 F.8.2 Bring all materials and equipme

26、nt to be used in prepar-ing test specimens to the specified test temperature, 6 3C6 5 F 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 temperature by fillingit with water at the

27、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, procedures for adjusting the mixingwater t

28、emperature 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 manufacturer on the package shall be used todeter

29、mine 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 testing. In either case, express the weight ofwat

30、er 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 C 305 or themortar mixer described in 10.1.2 shall be used for perfor

31、mancequalifications. 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 MixerThe mortar-mixingapparatus shall be as spe

33、When required, the purchaser must so specify in the purchase contract.C 1107/C 1107M 082mixer shall be provided with a bowl positioner to enableclearance of the largest sized aggregate in the mixture beingtested.10.1.2 Mortar MixerA 110 to 125-L 4 to 412-ft3 capac-ity horizontal shaft stationary dru

34、m mortar mixer (See Note 3)is required. 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. Themixing blades shall have adjustabl

35、e 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 inner surfaceof the mixing chamber b

36、elow 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 trowel or byreasonably striking with a

37、 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 responsibility to see that any equipmentin

38、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 classification and to determine the water conten

39、t 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 water con-tent, calculate the percent water from the packag

40、ing informa-tion and use that amount of water to prepare the grout mixture.If the manufacturer recommends maximum flow or most fluidconsistency, use the suggested water content as a starting pointand adjust water as necessary to achieve the maximum flow ormost fluid consistency stated on the package

41、. If the requiredconsistency has not been met, make additional adjustments toestimate the water content to use for the next batch. Discardcurrent batch and repeat with newly established water content.10.2.4 Place water in the bowl. Start the mixer at speed 1.Add the dry grout material to the water o

42、ver 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 procedures if recommended by the

43、 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 specimens from additional batchesof gro

44、ut 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 Procedure for Using The Mortar Mixer:10

45、.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 bags of material to produce atleast

46、 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 weighed contents of the packages t

47、o 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 water in asteady flow, sliding it

48、 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 manufacturer. If therequired consistency

49、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 mixing, discharge a portion of themateri
