Summary

During the last few years there has been a rapid increase in the use of volatilized silica as a raw material in a number of refractory products. Concretes based on microsilicablended high alumina cement were studied after drying and firing. Microstructure of the specimens was determined using scanning electron microscopy and X-ray microanalysis with phase analysis being carried out by X-ray diffraction. It is attempted to correlate the differences in microstructure to hot modulus of rupture data.
