2、, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers packaged dry, hydraulic cement grout (nonshrink) intended for use under appli
3、ed load (such as tosupport a structure, a machine, and the like) where a change in height below initial placement height is to be avoided.1.2 Grouts covered are composed of hydraulic cement, fine aggregate, and other ingredients. They require only the addition ofmixing water for use.1.3 The values s

The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.

30、the requirements prescribed in Table 1, except that the compressive-strength requirements do not have to be met at minimum usable temperature.6.4 Specimens for testing shall be stored continuously at the three required temperatures (23.0 6 2.0C 73.5 6 3.5F,maximum usable temperature specified by the
31、 manufacturer, and minimum usable temperature specified by the manufacturer).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 accorda
32、ncewith the mechanical-splitter method in Practice C702C702/C702M. For high-density grouts, adjust the mass to provide anequivalent 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 rec
33、ommended temperature limit and at atemperature corresponding to the minimum temperature stated by the manufacturer.8.1.2 For standard temperature testing, maintain the grout mixture and the testing equipment at a temperature of 23 6 2C 73.56 3.5F.8.2 Bring all materials and equipment to be used in p
34、reparing test specimens to the specified test temperature, 63C 65Fprior 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 temperat
35、ure and agitating 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 ach
36、ieve limitations imposed on the grout use temperatures. Use of this technique shall not abrogate the extendedmixing time requirement of this specification.9. Proportioning9.1 The minimum and maximum amount of water recommended by the manufacturer on the package shall be used to determineconformance
37、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 the weight of water so determined
38、 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 be used for performancequalificat
39、ions. 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 apparatus shall be as specified in Pr
40、actice 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) isrequired. The mortar mixer shall
41、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 inner surfaces of the mixing cha
42、mber. 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 the ends of the chamber. Thehoriz
43、ontal 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 electric motor-driven mixer is prefera
44、ble 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 in a physical or mechanical way
45、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 maximum flow or most fluid consis
46、tency.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 use that amount of water to prepa
47、re the grout mixture. If theC1107/C1107M 173manufacturer 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 consistency hasnot
48、 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 30 sec.After 1 m
49、in, 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.NOTE 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
