Abstract: This paper presents the determination of the rheological properties of cement grouts and the examination of the model jet grouting (JG) columns produced in the laboratory. Fine-grained cement (DMFC-800), ordinary Portland cement (CEM I), natural pozzolana admixtured cement (CEM II) and blast furnace slag (BFS) admixtured cement (CEM III) types were used. Grout mixtures with various water/cement (W/C) ratios were prepared and rheological tests were performed. Effects of cement characteristics and rheological properties of cement grouts on column dimensions, soilcrete strength were researched. Columns with the largest diameter were obtained with DMFC-800 cement. The primary parameter affecting the JG column diameter was cement grain size and the secondary parameter was grout viscosity. CEM III cement provided the highest compressive strength (28.5 MPa) in the long term. DMFC-800 provided remarkable strength (2-5 MPa) even with grouts containing high amount of water (W/C = 2.0-3.0). Grout stability affected the homogeneity of the soilcrete structure.
