17、SoakingMortar shall not soften norshow any evidence of fusion, and the shrinkage 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
18、Pyrometric Cone Equivalent (PCE)The PCE shall benot less than cone 32 (see 11.4).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, Typ
19、e 1Mortar shall show no 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,
20、when tempered with water, 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
21、 h.7.4.1 The mixed mortar 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
