1. 1. Evaluation of Real Time Grouting Control Theory Using a Varying Aperture Long Slot- VALS

   University essay from KTH/Jord- och bergmekanik

   Author : Elizaveta Pronina; [2018]
   Keywords : Grouting; Real Time Grouting Control theory-RTGC; Penetration Length; Cement-Based Grout; Varying Aperture Long Slot – VALS; hydraulic aperture;

   Abstract : The main goal of the grouting is to seal the fractures in the rock mass,improve the strength properties of the rock mass and decrease deformability. However,the overuse of the grouting should be avoided due mainly to economic reasons,optimizing the project time and sometimes severe environmental issues. READ MORE
