Deformation of unfired phosphate-bound refractories. Part 3. Deformation of hardened cements on heating and cooling

Deformation tests have been made on hardened cements. A difference from unhardened ones, which show considerable plastic (viscous) deformation, is that the hardened ones show mainly elastic strain with a small inelastic component at a temperature exceeding the preliminary heat treatment value. __________ Translated from Novye Ogneupory, No. 3, pp. 139–143, March, 2007.
