17、n, PA 19428-2959, United States.4.2 When the grout is to be used in contact with stressed tendons or other corrosion-sensitive, load-bearing structural members,the purchaser shall supply this information to the manufacturer and obtain assurances that the material meets relevant chloride,nitrite, nit

18、rate, sulfide, and sulfate requirements, and any other material limitations imposed by the applicable codes and standards(See Note 1).4.3 When the grout is to be used in abnormal or aggressive environments, the purchaser shall supply this information to themanufacturer and obtain assurance that the

19、grout has a successful history of performance in the same or similar exposures.NOTE 1Since all conditions of use cannot be anticipated, this specification requires nonshrink grout to exhibit no shrinkage when tested in alaboratory-controlled, moist-cured environment, and requires only the reporting

20、of the observed height change, usually shrinkage, when test specimensare subjected to some degree of drying. It is suggested that users consult with manufacturers on specific applications to determine the applicability ofspecific test results.5. Materials5.1 The materials used as ingredients in pack

21、aged, dry, grout include hydraulic cement, fine aggregate, and other ingredients.6. Performance Requirements6.1 Specimens shall be made from freshly mixed grout and from grout that has been retained in the mixer for the maximumusable working time allowed by the manufacturer. Specimens from both cond

22、itions shall meet the requirements prescribed in Table1.6.2 Specimens shall be prepared using materials and equipment at temperatures representing the maximum and minimum usabletemperatures specified by the manufacturer for his product. Specimens from both conditions shall meet the requirements pres

23、cribedin Table 1, except that the compressive-strength requirements do not have to be met at minimum usable temperature.6.3 Specimens for testing shall be prepared by combining the use of grout retained in the mixer as in 6.1 with the minimumand maximum as mixed and curing temperatures used in 6.2.

24、Specimens from these combinations of conditions shall meet therequirements of Table 1, except that the compressive-strength requirements do not have to be met at minimum usable temperature.6.4 All test specimens for performance evaluation shall be prepared using the highest water to solids ratio, ma

25、ximum flow, ormost fluid consistency stated on the package.7. Sampling7.1 Use whole packages of grout selected at random from the 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 from a whole package in accordancewith the mechan

26、ical-splitter method in Practice C702. For high-density grouts, adjust the mass to provide an equivalent volume.8. Batching8.1 Grout mixtures shall be produced in the following conditions:8.1.1 Batch grout mixtures at temperature conditions corresponding to the maximum recommended temperature limit

27、and at atemperature corresponding to the minimum temperature stated by the manufacturer.8.1.2For8.1.2 For standard temperature testing, maintain the grout mixture and the testing equipment at a temperature of 23 62 C 73.5 6 3.5 F.8.2 Bring all materials and equipment to be used in preparing test spe

28、cimens to the specified test temperature, 6 3C6 5 Fprior to use.8.2.1 When the controlled-environment test room is too small to accommodate large equipment, immediately prior to use, bringthe mixer to the desired testing temperature by filling it with water at the appropriate temperature and agitati

29、ng it by turning themixer on. When this water has stabilized at the desired temperature, discard it and start preparing the batch immediately.8.3 The manufacturer is not prohibited from including, in the package instructions, procedures for adjusting the mixing watertemperature to achieve limitation

30、s imposed on the grout use temperatures. Use of this technique shall not abrogate the extendedTABLE 1 Performance RequirementsCompressiveStrength,minMPa psi1 dayA7.0 10003 day 17.0 25007 day 24.0 350028 day 34.0 5000Early Age Height ChangeMax % Final Set + 4.0Height Change of Moist CuredHardened Gro

Proportioning9.1 The minimum and maximum amount of water recommended by the manufacturer on the package shall

32、 be used to determineconformance with the requirements of this specification. If the manufacturer provides maximum flow (thinnest consistency)information on the package, conduct consistency tests to an accuracy of 65 % to determine the amount of water to be added fortesting. In either case, express

33、the weight of water so determined as a ratio of water to dry grout material by weight. If both aregiven, make tests at whichever involves the larger amount of water by ratio of dry grout mixture.10. Mixing10.1 Either the mixer described in Practice C305 or the mortar mixer described in 10.1.2 shall

34、be used for performancequalifications. In the event of a dispute, the mixer described in 10.1.2 shall be used for the referee test.NOTE 2The referee test is a test made to settle disagreement as to the conformance to the specified requirements.10.1.1 Bench Scale Epicyclic MixerThe mortar-mixing appa

35、ratus shall be as specified in Practice C305. However, the mixershall be provided with a bowl positioner to enable clearance of the largest sized aggregate in the mixture being tested.10.1.2 Mortar MixerA110 to 125-L 4 to 412-ft3 capacity horizontal shaft stationary drum mortar mixer (See Note 3) is

36、required. The mortar mixer shall have a metal shell with horizontal mixing blades. The mixing blades shall be angled so thatadjacent paddle arms reverse the flow of the grout in the mixing drum during rotation of the horizontal shaft. The mixing bladesshall have adjustable wiper blades that wipe the

37、 inner surfaces of the mixing chamber. The wiper blades shall be rubber or otherflexible, wear-resistant material that does not deleteriously react with the grout mixture. The wiper blades shall be adjusted tocontinuously wipe the curved inner surface of the mixing chamber below the grout level and

38、the ends of the chamber. Thehorizontal shaft shall rotate the mixing paddles at 28 to 35 r/min. The mixer shall be clean, pre-wetted, and drained and essentiallyfree of hardened mortar and other foreign material that can be removed with a trowel or by reasonably striking with a hammer.NOTE 3An elect

39、ric motor-driven mixer is preferable in the laboratory to avoid noise and exhaust fumes. For greater safety, the mixer should beequipped with a lever-operated clutch. While these comments are selected safety precautions, it is the users responsibility to see that any equipment inuse is not hazardous

40、 in a physical or mechanical way to operators and attendant 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 consistency classification and to determine the water content of grout testedat

41、maximum flow or most fluid consistency.10.2.2 Weigh all grout on a balance or on a platform scale to the nearest 0.1 %.10.2.3 Measure the water by mass or volume to the nearest 0.1 %. If the manufacturer recommends maximum water content,calculate the percent water from the packaging information and

42、use that amount of water to prepare the grout mixture. If themanufacturer recommends maximum flow or most fluid consistency, use the suggested water content as a starting point and adjustwater as necessary to achieve the maximum flow or most fluid consistency stated on the package. If the required c

43、onsistency hasnot been met, make additional adjustments to estimate the water content to use for the next batch. Discard current batch and repeatwith 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 over approximately

44、 30 sec.After 1 min, stop the mixer for 15 sec and scrape into the batch any grout that may have collected on the side of the bowl. Switchto speed 2 and mix for a total of 5 min as measured from first contact of dry material with water. Use other mixing proceduresif recommended by the manufacturer.N

45、OTE 4It is advisable to cover the bowl with a lid while mixing. A metal disc in which a slit has been cut to accommodate the mixer shaft has beenfound suitable. If excessive splash-over occurs, a larger mixer should be used.10.2.5 Prepare required specimens from additional batches of grout as needed

46、. Use the water content established above for allsuccessive batches. When testing grout at the end of its working time, a separate batch of grout shall be mixed continually untilthe time of test unless otherwise recommended by the manufacturer.10.3 Procedure for Using The Mortar Mixer:10.3.1 Prepare

47、 all specimens from a single batch of grout using the horizontal shaft stationary drum mortar mixer. Perform teststo verify compliance with performance requirements.10.3.2 With materials and equipment brought to the testing temperature, use enough whole bags of material to produce at least56 L 2 ft3

48、 of mixed grout. Use this batch for both freshly-mixed and delayed-mixed testing at one specified temperature. Placethe total required amount of mixing water in the mixer (See Note 5).10.3.2.1 When testing a grout to a maximum water to solids ratio, use the weighed contents of the packages to determ

49、ine theamount of water to be used.10.3.2.2 When testing a grout to a maximum recommended flow or most fluid consistency, adjust the water content at the timeof mixing to achieve the recommended consistency. With the mixer running, add the grout material to the water in a steady flow,sliding it into the mixer along the side away from the discharge. After mixing for 1 min, stop the mixer for not more than 30 sand scrape down the sides and blades. Mix for an additional 5 min after all the dry material has been added, unless otherwiseC1107/C110
