This specification covers the requirements for chemical-resistant resin grouts used for filling joints of chemical-resistant brick or tile units. The liquid resins may be furan, epoxy, vinyl ester, or other resins capable of forming chemical-resistant grout after mixing with a suitable setting agent and filler. Fillers may be silica, carbon, or other chemical resistant materials and may be supplied as a separate component or as a premix with the liquid resin and/or setting agent. Setting agents may include amines, polyamides, acids, or other reactants and may be supplied as a separate component or as a constituent of the filler. All materials should conform to the prescribed setting time, compressive strength, tensile strength, water absorption and linear shrinkage.

1.1 This specification covers the requirements for chemical-resistant resin grouts for filling joints of chemical-resistant brick or tile units. For use of these materials, see Practice C 723. (For mortars, see Specification C 395.)

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.

Note 1—Resin grouts and mortars are differentiated as follows: Resin grouts are applied to the joints, generally ¼ in. (6 mm) wide, after the brick or tile are set in place and the setting bed has hardened (grouting or tilesetter's method). Resin mortars are trowelled onto the brick or tile in sufficient quantity to achieve a ¹/₈-in. (3-mm) thick joint after the brick or tile are laid in place (buttering or bricklayer's method).
