This specification covers the requirements for chemical-resistant sulfur mortar for bonding chemical-resistant brick or tile. The chemical composition shall conform to the required percentage of sulfur and inert filler. The fillers are usually carbon or silica. A general guide to chemical resistance of sulfur mortars is given. The sulfur mortar shall conform to the following physical requirements: tendency of filler to settle, tensile strength, compressive strength, flexural strength, strength retained after thermal shock test, bond strength, and absorption. Test for the physical requirements of the material shall be performed.

1.1 This specification covers the requirements for chemical-resistant sulfur mortar, which must be heated and molten to be used, for bonding chemical-resistant brick or tile. For the use of these materials, see Practice C 386.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Section 7 for specific safety hazard.
