ABSTRACT:
A high strength mortar has been developed for use with silica brick, in the construction of coke-oven heating walls. When fired to conventional coke oven temperatures of about 1100.degree. C., the mortar develops a tensile strength within the mortar itself, and a tensile bond to the silica brick, which exceeds the tensile strength of the silica brick. The mortar is composed of three primary solid constituents: 25 to 88 percent SiO.sub.2, 6 to 65 percent Al.sub.2 O.sub.3 and 4 to 12 percent P.sub.2 O.sub.5. To achieve such high tensile strength, the other solid constituents must be maintained at a minimum, desirably less than four percent and preferably less than two percent. Use of the high strength mortar permits construction of coke oven walls which can withstand significantly increased coking pressures--resulting in two significant benefits; (i) productivity increases of the order of 10 to 15 percent and (ii) doubling the service life of a coke oven wall.
