Development of grouting method of fine sand with …

The purpose of our work is to develop grouting methods with ultrafine cement (the average particle size 1.5ìm) grout. The authors conducted both laboratory and field grouting tests. As a result, the grout permeated into a one-meter long artificial ground composed of fine sand, where conventional superfine cement grout was not able to permeate.

Experimental Study on Groutability of Sand Layer ...

2021-3-16 · Permeation grouting is widely used in grouting engineering because of its low grouting pressure and minor disturbance to the stratum. However, influenced by the complex properties of sand layer and slurry, an accurate prediction of the groutability of the sand layer remains to be a hard work. In this paper, the permeability of sand layer is studied based on a self-designed permeation grouting ...
