16、tional Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.15.1.1 Type 1, DryMortar shall be furnished dry and shallbe ready for use as soon as mixed with water. Mortar, afterbeing mixed with water and then dried, shall be capable

17、ofbeing remixed with water.5.1.2 Type 2, WetMortar shall be furnished ready for useat a trowelling consistency and shall be easily mixed withwater to a dipping consistency.6. Performance Requirements6.1 Resistance to Heat SoakingMortar shall not soften norshow any evidence of fusion, and the shrinka

18、ge shall not begreater than hairline cracks when tested as specified in 11.2.6.2 Bonding StrengthThe average modulus of rupture atthe brick joint when tested as specified in 11.3 shall be not lessthan shown in Table 1.6.3 Pyrometric Cone Equivalent (PCE)The PCE shall benot less than cone 32 (see 11.

19、4).7. Requirements7.1 FinenessMortar shall be ground to such fineness thatnot more than 5 % shall be retained on a No. 40 ASTM sieve,and not more than 0.5 % shall be held on a No. 30ASTM sieve(see 11.1).7.2 Shelf Life, Type 1Mortar shall show no deteriorationafter 1 years storage.7.3 Shelf Life, Typ

20、e 2At any time within one year ofshipment from the supplier, the mortar in a previously un-opened container shall not have stiffened to such an extent asto interfere with its easy removal and mixing.7.4 ConsistencyMortar, when tempered with water, shallbe of such consistency that it will be suitable

21、 for spreadingeasily with a trowel or for dipping and for laying refractorybrick and bonding them together upon drying and uponsubsequent heating at furnace temperatures. Mortar shall retainthis degree of workability for 2 h.7.4.1 The mixed mortar shall have sufficient water retentionto permit a116-

22、in. (2-mm) joint to be made with a trowellingconsistency, but not allow the newly laid brick to float out ofposition.8. Workmanship8.1 Workmanship shall be first class in every respect. Thereshall be no foreign material or caked aggregate lumps in themortar. Wet mortar shall be easily removed from t

23、he containerand shall mix easily to a uniform trowelling consistency.9. Sampling9.1 An inspection lot for tests and inspections shall consistof all material manufactured at essentially the same time and ofthe same type offered for delivery at one time.9.2 For the tests specified in 11.1 through 11.4

24、, the sampleunit shall be 15 lb (7 kg) of mortar. No fewer than three sampleunits shall be randomly selected throughout the lot. No morethan one sample shall be drawn from any one container.9.2.1 The test sample shall be a 45-lb (20-kg) composite ofthe randomly selected sample units. Two or more det

25、ermina-tions as applicable (see Table 2) shall be performed on thecomposite. There shall be no evidence of failure to meet thespecified unit or average requirements.9.3 The PCE shall be determined on two cones of differentsamples from each lot. If both cones fail, this shall be cause forrejection wi

26、thout retest. If either cone fails, three additionalcones shall be made, each from a different sample. If any oneof the three retest cones fails, this shall be cause for rejection.10. Specimen Preparation10.1 The entire mortar sample for testing shall be thor-oughly mixed to ensure uniformity before

27、 any portion is takenfor tests. The selected portion of Type 1 (dry) mortar shall bemixed with water to a trowelling consistency for the tests of11.2 and 11.3. Storage time after water mixing shall be 20 to30minutes.10.2 For the test specified in 11.3, brick-mortar joints shallbe prepared in accorda

28、nce with Test Method C198, except thatrefractory bricks, conforming to Classification C27,60%High-Alumina, shall be used and shall be cut in half. The twohalves of each brick shall be placed in a device suitable forbringing, with a straight motion, the molded ends together withthe faces parallel at

29、all times to form a bond.10.2.1 Asmall quantity of mortar shall be spread by a trowelon the upper face forming the bond to ensure intimate contact.Sufficient mortar to give a18-in. (3-mm) thick layer shall bespread evenly on the lower bond forming face and the upperhalf shall be lowered until it is1

30、16 in. (2 mm) from the lowerhalf. The excess mortar shall be cut from the joint, flush withthe sides of the brick. The unit thus formed shall be removedat once from the bond-forming machine. The bond specimensshall be allowed to air-dry for 20 to 24 hours.11. Test Methods11.1 FinenessThe fineness te

31、st shall be made in accor-dance with Test Methods C92.11.2 Heat Soak:11.2.1 A pier of refractory brick, conforming to Classifica-tion C27, super-duty, laid up with the test mortar shall beprepared and heated at 2910F (1588C) for 5 hours inaccordance with Test Method C199.11.2.2 The cooled pier shall

32、 be examined for evidence ofshrinkage, softening, or fusion of the mortar. One or moremortar joints shall be broken and the freshly broken mortarsurface shall be viewed from various angles. Any shininess orlight flash at the mortar surface shall be considered anindication of excessive fusion.11.3 Bo

33、nding Strength:11.3.1 Five bond specimens (see 10.2) shall be placed in anoven operating at 230F (110C) for at least 16 hours; fivebond specimens shall be held at each of the other testTABLE 1 Bonding Strength of MortarTemperatures, F (C)Average Modulus of Rupture,psi (kPa), min230 (110) 200 (1400)1
