1、Designation: C1655 06 (Reapproved 2011)Standard Classification ofFireclay and High-Alumina Mortars1This standard is issued under the fixed designation C1655; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision

2、. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification pertains to fireclay and high-aluminarefractory mortars that can be trowelled, dipped or painted tojoin or coat

3、 refractory bricks and shapes.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address safety co

4、n-cerns, if any, associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.

5、ctory MortarsC27 Classification of Fireclay and High-Alumina Refrac-tory Brick3. Significance and Use3.1 Refractory mortars are used for laying, bonding andcoating refractory brick. They become an integral part of theresulting refractory lining or structure. Therefore, such mortarsshould be selected

6、 in order to closely match those of the brick.A classification system is provided for use in producing,purchasing and using different types of refractory mortars.4. Basis of Classification4.1 Heat-Setting Mortars This class hardens at elevatedtemperature by forming a ceramic bond. The minimum tem-pe

7、rature required for forming the ceramic bond is usually atleast 2000 F (1095 C).4.2 Air-Setting Mortars This class initially hardens atambient temperatures in contact with air and forms a strongbond upon drying at 230 F (110 C).4.3 Chemically Bonded Mortars Mortars in this classcannot be said to tru

8、ly airset, since they require some heatingto initiate hardening. However, they harden at temperatureslower than those required for ceramic bonding. A commonexample of a chemically bonded mortar is a phosphate-bondedmortar.4.4 Each of the above classes of mortar are further classifiedby the condition

9、 in which they are supplied:4.4.1 Dry Mortars This class is supplied dry and must bemixed with water prior to use.4.4.2 Wet Mortars This class is supplied in a ready for use.4.5 The above classes of mortars are further classified forusage with a particular type of brick as prescribed in Table 1.5. T

10、est Methods5.1 The properties enumerated in this classification shall bedetermined in accordance with the following ASTM testmethods:5.1.1 Pier Test Test Method C199. For medium-duty,high-duty, super-duty and high-alumina mortar classes testwith appropriate brick that meet requirements specified in

11、TestMethod C199. For high-alumina mortars in the 80 %, 85 %,90 %, and 99 % classes test with high-alumina brick from theappropriate class meeting the requirements specified in Clas-sification C27.5.1.2 Alumina Content XRF and ICP after calcining to1830 F (1000 C).6. Retests6.1 Because of possible va

12、riables that may result fromsampling or an unsatisfactory reproducibility of tests bydifferent laboratories, the material may be resampled andretested at the request of either purchaser or the manufacturer.This could apply where the first test results may not conform tothe requirements prescribed in

13、 this classification. Therefore,the final results to be used shall be the average of at least twoseries of tests, each of which has been obtained by followingthe testing procedures in detail.7.
