1、Designation: C 1054 03 (Reapproved 2008)Standard Practice forPressing and Drying Refractory Plastic and Ramming MixSpecimens1This standard is issued under the fixed designation C 1054; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision
2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the pressing and drying of chemi-cally and nonchemically bonded aluminum-silicate
3、and highalumina plastic and ramming mix refractory specimens classi-fied in accordance with Classification C 673.1.2 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.3 This standard does not purport to address all of t
4、hesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use3.1 This practice is useful f
10、or producing uniform specimensof refractory plastics and ramming mixes for use in standardASTM tests. Samples thus formed may be used for refereetesting when setting specifications between producer and user.Forming parameters such as sample size, workability, andforming pressure should be agreed upo
11、n and specified in thereport when referee testing.3.2 This practice is applicable for preparing test specimensof various sizes. Note that 9 by 412 by 212 in. (228 by 114 by64-mm) samples, because of their large cross-section, have agreater tendency to form flaws during pressing, handling, anddrying
12、than smaller cross-sectional samples.3.3 Other tests for which these specimens may be usedencompass, but are not limited to, the following ASTMstandards: Method C16, Test Methods C20, Test MethodC113, Test Methods C 133, Test Method C 179, Test MethodC 288, Test Method C 417, Test Method C 577, Test

It is not intended to duplicate all fieldinstallation co
16、nditions.3.5 Variations in workability as determined by Test MethodC 181 can significantly affect the number of flaws contained ina specimen. For comparison testing between two laboratories,the workability level should be established by mutual agree-ment.3.6 This practice is not intended for prepari
17、ng specimens ofbasic ramming mixes, anhydrous tap-hole mixes, nor resinbonded mixes.4. Apparatus4.1 Power Press, preferably of the hydraulic type, equippedwith suitable molds for forming specimens of the required size(Note 1). The press should be capable of a minimum of 1500psi (10.34 MPa) pressure
18、when forming the largest cross-sectional area specimen.NOTE 1It may be advisable to have the molds slightly oversized sothat, after drying, the specimens will be close to the required size for thespecific test.4.2 Drying Oven, preferably forced-draft rather than naturalconvection, capable of reachin

The cross-sectional dimensions of these pieces will vary,depending on the side dimensions of the bar being pressed.5. Sampling5.1 The
21、container or package should not be opened prior totesting to ensure that the contents do not dry out.5.2 At the time of the test, the sample should be between 65and 75F (18 and 24C). Measure the temperature by insertingthe full length of the thermometer stem into the material. Noteand record tempera
22、ture when the reading is constant.6. Procedure6.1 Workability Index Measurement (Note 2)Determineand report workability of plastics at the time of pressing inaccordance with the procedure described in Test Method C 181(Note 3).NOTE 2A workability index between 17 and 23 is the optimum rangefor press
23、ing samples with a minimum amount of flaws. If higherworkability material is used in referee tests between two or morelaboratories, the workability should be the same, (63 %), for the materialbeing tested.NOTE 3Since no suitable standard test exists for gaging the workabil-ity of ramming mixes, part
