Industrial slag portland cements produced from granular magnesia slags were studied concurrently with laboratory slag portland cements. All passed the autoclave tests for uniformity of volume change under a pressure of 20 kb/sq cm. There were virtually no deformations in 180-day specimens. Study results show that the strength of slag portland cement (SPC) increases steadily, and after 2 years exceeds the classical 28-day strength by a factor of 1.5-2.0. As compared with the conventional SPCs, the magnesia SPCs follow a high strength gain indicator from 28 to 360 days; this has a positive effect on massive concrete placed in hydraulic structures. As compared with th conventional SPCs the magnesia SPCs exhibit an even lower heat liberation, amounting to 34 and 45 cal/g after 3 and 7 days of hardening respectively. The quality of magnesia SPC was assessed from comparative corrosion-resistance tests, and the structural-engineering properties of the magnesia SPC were tested directly in concrete. The investigations confirm that magnesia-slag-based slag portland cements satisfy the technical specifications and that they are suitable for massive concrete in hydraulic structures.
