• Abstract:
  Through the testing involved in this project, it has been shown that concrete made with Dacotah Type IPM cement has compressive and flexural strengths approximately 10 - 12% lower than standard Type I/II cement mixtures. This is probably due to the fact that 10% of the cement is replaced with a natural pozzolan. Cores taken from field test sections showed compressive strengths 20 to 40% lower than strengths of laboratory concrete specimens. Time of set for the Type IPM cement is lower than that of Type I/II, mainly due to Type IPM cement being finer than Type I/II. Freeze/thaw and deicer scaling durability of this new cement is equal to the standard Type I/II used as a control.
