16、PCE shall benot less than cone 32 (see 11.4).7. Requirements 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
17、 deteriorationafter 1 years storage.7.3 Shelf Life, Type 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 wate
18、r, shallbe of such consistency that it will be suitable 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 mort
19、ar shall have sufficient water retentionto permit a116-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
20、in themortar. Wet mortar shall be easily removed from the 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 on
21、e time.9.2 For the tests specified in 11.1 through 11.4, 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) composit
22、e ofthe randomly selected sample units. Two or more determina-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.
23、If both cones fail, this shall be cause forrejection without retest. If either cone fails, three additionalcones shall be made, each from a different sample. If any oneof the three retest cones fail, this shall be cause for rejection.10. Specimen Preparation10.1 The entire mortar sample for testing
24、shall be thor-oughly mixed to ensure uniformity before 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 11.3.10.2 For the test specified in 11.3, brick-mortar joints shallbe prepared in accordance
25、 with Test Method C 198, except thatrefractory bricks, conforming to Classification C27, super-duty, shall be used and shall be cut in half. The two halves ofeach brick shall be placed in a device suitable for bringing,with a straight motion, the molded ends together with the facesparallel at all ti
26、mes 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 is116 in.
27、 (2 mm) from the lowerhalf. The excess mortar shall be cut from the joint, flush withTABLE 1 Bonding Strength of MortarTemperatures, F (C)Average Modulus of Rupture,psi (kPa), min230 (110) 200 (1400)1000 (538) 100 (700)2000 (1093) 100 (700)TABLE 2 Testing RequirementsCharacteristicSpecificationRefer
