17、essful 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 hei
18、ght 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.

30、 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 73.5 6 3.5F.8.2 Bring all materials and equipment to be used in prepar-ing test specimens to the sp
31、ecified 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 temperature by fillingit with water at the appropriate temperature and agitating it byturning the
32、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 temperature to achieve limitations imposed on the groutu
33、se 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 todetermine conformance with the requirements of this specifi-
34、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 ofwater so determined as a ratio of water to dry grout mater
35、ial 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 described in 10.1.2 shall be used for performancequalifications. In the event of a dispute, the mixe
36、r 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 specified in Practice C305. However, themixer shall be prov
37、ided with a bowl positioner to enableclearance of the largest sized aggregate in the mixture beingtested.10.1.2 Mortar MixerA110 to 125-L 4 to 412-ft3 capacityhorizontal shaft stationary drum mortar mixer (see Note 3)isrequired. The mortar mixer shall have a metal shell withhorizontal mixing blades.
38、 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 adjustable wiper blades that wipe theinner surfaces of the mixing chamber. The wiper blades shallbe rubber or other flex
39、ible, 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 below the grout level and the ends ofthe chamber. The horizontal shaft shall rotate the mixingpaddles at 28 to 3
40、5 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 hammer.NOTE 3An electric motor-driven mixer is preferable in the laboratoryto avoid noise and exhaust fumes. F
41、or 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 use is not hazardous in a physical or mechanical way to operators andattendant personnel, and that safe work pr
42、actices 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 content of grouttested at maximum flow or most fluid consistency.10.2.2 Weigh all grout on a balance or on a platform
43、 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 the percent water from the packaging infor-mation and use that amount of water to prepare the groutmixture. If the manufacturer recommends maximum
44、 flow ormost fluid consistency, use the suggested water content as astarting point and adjust water as necessary to achieve themaximum flow or most fluid consistency stated on the package.If the required consistency has not been met, make additionaladjustments to estimate the water content to use fo
45、r 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 dry 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 c
46、ollected 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 manufacturer.NOTE 4It is advisable to cover the bowl with a lid while mixing. Ametal disc in which a slit has bee
47、n 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 grout as needed. Use the water content established above forall successive batches. When testing grout at the end of
48、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:10.3.1 Prepare all specimens from a single batch of groutusing the horizontal shaft stationary drum mortar mixer.Per
49、form 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 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).C1107/C1107M 14a310.3.2.1 When testing a grout to a maximum water to solidsratio, use the weighed contents of the packages to dete
