SLAG PORTLAND CEMENT FOR HYDRAULIC STRUCTURES OPERATING UNDER SEVERE CLIMATIC CONDITIONS

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.
