In this context, some experimental and analytical analyses were conducted and their results were presented. In terms of rheological and workability tests, the test program included 28 different mixtures having 0% (for control purposes), 5%, 10%, 15%, 20%, 25% and 30% bottom ash content and four water to binder ratios (w/b = 0.75,1.00, 1.25 and 1.50). Plastic viscosity, apparent viscosity, and the yield stress of the mixtures based on rheological properties were measured for all mixtures. At the same time, marsh cone flow time, plate cohesion, and mini slump diameter in terms of workability features were obtained. In second part of this study, all rheological properties obtained from the mixtures were used for evaluating permeation grout method based on two analytical flow models (radial and spherical flow models). All test results showed that rheological parameters (especially plastic viscosity) and workability properties of the cement based grouts incorporated with BA are very important for determining of the permeation grouting design parameters such as injection pressure.
