| Abstract | Hydration and strength development characteristics of high alumina cement (HAC) containing sodium sulfate and a variety of different zeolites were studied. The zeolites obtained from different sources included different types containing clinoptilolite, chabazite, stilbite, and natrolite. The one-day compressive strength of HAC mortars containing a commercially available zeolite and sodium sulfate was as high as 60 MPQ. No strength reduction occurred in the HAC mortars water-cured at 38 C for 330 days. Hydrogarnet formation was significantly inhibited. Clinoptilolite or chabazite-based zeolites in combination with sodium sulfate were more effective in preventing the formation of hydroganet in HAC paste than stilbite or natrolite-based zeolites. Zeolite alone was not able to prevent the hydrogarnet/formation in the HAC paste. Chabazite was the most effective zeolite in promoting strätlingite formation in the HAC paste. |
