RAYA MORTARS

RAYA MORTARS

Refractory mortars are joint materials used in brickwork or for joining prefabricated parts. They are supplied in dry form and after addition of mixing liquid- water-are brought to the ready for use consistency.

Mortars are either hydraulically, ceramic or ceramic-chemically bound.

The former is suitable where higher strength is necessary or desired in the lower temperatures; on the other hand Ceramic-chemical bond reach the final strength after some definite higher temperatures although some degree of “set” is reached in ambient temperature.
