    ASTM C1655

    Significance and Use

    Refractory mortars are used for laying, bonding and coating refractory brick. They become an integral part of the resulting refractory lining or structure. Therefore, such mortars should be selected 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.

    1. Scope

    1.1 This classification pertains to fireclay and high-alumina refractory mortars that can be trowelled, dipped or painted to join or coat refractory bricks and shapes.

    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 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.
