Conclusions Phase analyses by x-ray methods, petrography, mass-spectrometry, chemical analyses, and paper chromatography were used in an investigation of the composition of the phosphate bond of a nonshrinking Gunite intended for the guniting of the roof of open-hearth furnaces during the downtime for repairs. The phosphate bond is a complex mixture of ortho-, pyro-, poly-, and cyclic phosphates. The amount of orthophosphates in the bond increases appreciably, while that of the chain (¯n 〈 20) and cyclic phosphates decreases with an increase in the heat-treatment temperature. It was established that the added sodium polyphosphate reacts more effectively with the magnesite component of the Gunite.
