"The insistent demand for higher grade refractories has resulted in the manufacture of a product which will withstand higher temperatures, have greater slag resistance, greater resistance to spalling action and deformation under load. These better grades of refractory materials have been developed as the result of extensive research on the part of the manufacturers. In order that these higher quality refractories may be employed with the best results, it is necessary that they be set with a refractory cement which also possesses these desirable properties. The commercial refractory cements may be divided into two classes according to their method of set, namely, 1. Heat setting 2. Cold setting or air setting. The heat-setting cement has very little strength after air-drying but attains a high strength after the vitrified bond is developed upon firing. The cold-setting or air-setting cement is coming into more prominence because it develops high strength upon air-drying as well as in the fired condition...At the present time there is still a need for a cement that will withstand still higher temperatures. It was thought that perhaps another silicate, such as potassium silicate, might enhance the P. C. E. value of the cement and still not detract from the other desirable properties of the silicate of soda cold-set refractory cement. With this objective in mind this investigation was planned"--Introduction, page 1-2.
