Abstract
The three most common cement s for rock injection in Norway were characterized in terms of grout flow properties, stability and initial set for w/c = 1.2, 1.0, 0.8 and 0.6 at 8 and 20°C. The fineness was characterized by Blaine, BET and particle size distribution (PSD). The test methods w ere bleeding, consistency (ring and Marsh Cone), setting by Vic at and temperature evolution in insulated cup. Additional rheology tests with parallel plate rheometer and isothermal calorimetry for hydration evolution were performed for mixes at 20°C only. Only one of the three cements tested could be utilized at all w /c levels.
