1. 1. State of the Art Report on Cement Based Grout Properties and Dynamic Grouting

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Bowen Meng; [2021]
   Nyckelord :Dynamic grouting; filtration; rheology; grouting phase;

   Sammanfattning : Dynamic grouting in rock mass has been studied since 1985 while desired penetration in rock masses with fine fractures is still a challenge because of uncertainty and complexity in the grouting process. This has attracted the attention of researchers in different countries and regions, especially in some Nordic countries such as Sweden. LÄS MER

3. 2. Dispersion of cement-based grout with ultrasound and conventional laboratory dissolvers

   Master-uppsats, KTH/Byggvetenskap

   Författare :Antranik Karamanoukian; [2020]
   Nyckelord :ultrafine cement grout; microfine cement grout; dispersion; additives; ultrasound dissolver; laboratory dissolver; ultrafint cementbruk; mikrofin cementbruk; dispergering; tillsatser; ultraljud apparat; laboratorieblandaren;

   Sammanfattning : In any underground facilities especially tunnels, it is essential to seal the area against water ingress and leakage of reserved materials. Grouting is a common method used to seal rocks around tunnels, successful grouting reduces the duration and cost of the construction, guarantees better working environment and higher safety, minimizes the maintenance and most important decreases the corresponding environmental hazards significantly.

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

   Master-uppsats, KTH/Jord- och bergmekanik

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

   Sammanfattning : 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. LÄS MER

5. 4. Application of Dynamic Grouting to Improve the Grout Spread Using Varying Aperture Long Slot (VALS) : AN EXPERIMENTAL STUDY

   Master-uppsats, KTH/Jord- och bergmekanik; KTH/Byggvetenskap

   Författare :Robabeh Hosseini; Yalta Steven; [2018]
   Nyckelord :grout penetrability; filtration tendency; varying aperture long slot; sealing; cement-based grout; dynamic grouting; bruksinträngningsförmåga; filtrationstendens; VALS; tätning; cementbaserade injekteringsmedel; dynamisk injektering;

   Sammanfattning : In the past centuries, grouting has been one of the most common techniques in geotechnical engineering to strengthen and seal underground structures. Concerning increasing demands for tightness and cost efficiency, cement-based grout has been one the most frequent used materials. LÄS MER

7. 5. Evaluation of "GIN method" at Two fans of City banan project in Stockholm

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Mehran Neshati Sani; [2015]
   Nyckelord :grouting; GIN method; cement; jacking; penetration; pressure; volume intake;

   Sammanfattning : An underground installation with too much inflow can lead to dangerous consequences for around environment, therefore a well-sealed construction results in appropriate inflows. To mitigate movement of ground water table in underground constructions, it is necessary to seal the rock mass by grout injection. LÄS MER
