Experimental investigation of pressure grouting in

Pressure grouting technology has been widely adopted in ground improvement and soil stabilization. To better understand the grout evolution and diffusion process upon pressure grouting injection in sand, laboratory-scale tests were carried out on loose sand under confined boundary conditions, with different grout water/cement (w/c) ratios (0.5 and 1) and soil degrees of saturation (ranging

The efficiency of compensation grouting in sands

Physical model experiments on compensation grouting in sands were performed in two different setups (Cambridge and Delft). The effect of water-cement (w/c) ratio, bentonite content (b.c.) and injection rate on compensation efficiency was investigated. Results show a considerable drop in compensation efficiency resulted from reducing the soil density.

Compensation Grouting in Sand : Experiments, Field

The evaluation of field measurements shows the influence of soil disturbance. Soil disturbance in a layer of sand may lead to a decrease in density of the sand and compensation grouting in such a layer will have a lower efficiency (a lot of grout has to be injected to create some heave) and long term settlements are possible.
