Tests of Trief Cement and Laboratory-Ground Water Quenched, Blast-Furnace Slag Cement
Trief patented-process cement is a material made by wet-grinding basic, granulated, blast-furnace slag. The material may be used as ground, or dried for storage. A catalyst is added when the cement is used. Petrographic analyses indicated that the laboratory-ground slag was slightly more uniform in composition than the Trief cement. Trief cement and laboratory-ground slag cement blended with portland cement showed negligible expansion in sodium sulfate solution. Trief cement generally exhibited somewhat higher strengths at all ages after obtaining final set than did laboratory-ground slag cement. Trief cement concrete without air (not tested with air because of lack of material) and laboratory-ground slag cement concrete, with or without entrained air, exhibited extremely low resistance to accelerated freezing-and-thawing.
