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

   University essay from KTH/Jord- och bergmekanik

   Author : Bowen Meng; [2021]
   Keywords : Dynamic grouting; filtration; rheology; grouting phase;

   Abstract : 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. READ MORE

   Abstract : The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. READ MORE

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

   University essay from KTH/Byggvetenskap

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

   Abstract : 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.

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

   University essay from KTH/Jord- och bergmekanik; KTH/Byggvetenskap

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

   Abstract : 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. READ MORE

6. 5. Evaluating and Comparing of Three Penetrability Measuring Devices : Modified Filter Pump, Modified Penetrability Meter, and Short Slot

   University essay from KTH/Jord- och bergmekanik

   Author : Saman Ali Akbar; Manar Al-Naddaf; [2015]
   Keywords : grouting; penetrability; filtration; fitter pump; penetrability meter; short slot; cement-based grout;

   Abstract : Rock grouting is a commonly used process for sealing rocks in tunnels to reduce water ingress. In order to achieve sufficient sealing level the grout must effectively penetrate into rock fractures while the limiting factor is filtration of cement based grout. READ MORE
