1. 1. Development of grout for deep shaft

   University essay from KTH/Byggteknik och design

   Author : Karl Lindberg; Adam von Krusenstierna; [2021]
   Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

   Abstract : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. READ MORE

3. 2. Evaluation of high pressures in grouting using RTGC - a case study

   University essay from KTH/Jord- och bergmekanik

   Author : Simon Nikolaev; [2015]
   Keywords : grouting; grouting pressures; tunnelling project; RTGC-theory; injektering; injekteringstryck; tunnelprojekt; RTGC-teorin;

   Abstract : “Real time grouting control method” är ett koncept för att övervaka och bedöma spridningen av injekteringsbruk under injektering. Målet är att kunna använda penetrationsavstånd som stopkriterium och att kunna övervaka hur injekteringsarbetet fortskrider i realtid, vilket skulle göra injekteringsarbetet mer tids- och kostnadseffektivt.

4. 3. 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

5. 4. Evaluation of a concrete plug : From the Dome Plug Experiment DOMPLU at Äspö HRL

   University essay from KTH/Betongbyggnad

   Author : Anders Kristiansson; [2014]
   Keywords : DOMPLU; DOPAS; concrete plug; KBS-3V; measurement; full scale test; SKB; nuclear waste repository; DOMPLU; DOPAS; betongplugg; KBS-3V; mätningar; fullskaleförsök; SKB; kärnavfallsförvaring;

   Abstract : In SKB’s Äspö Hard Rock Laboratory (HRL) a full scale test of a concrete plug,part of a sealing structure for the depository of spent nuclear fuel, has been carriedout. The aim of this thesis is to evaluate the behavior of the concrete plug and howit corresponds to assumptions made during the design. READ MORE
