Abstract
The invention discloses cement rotary kiln firebrick laying mortar which comprises the following components: by weight, 80-85% of aggregate, 14-19% of a binder and 1-3% of a coagulation accelerator. By selecting a reasonable ratio of the aggregate to the binder, each element in the fireproof mortar is used at the operating temperature to firmly combine firebricks together through a series of chemical reactions or ceramic reactions between the fireproof mortar and firebricks. Thus, firebricks made from different materials are laid to form an integral body.
