  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

  2. 2. Grouting Design Considering Different Geological Conditions : Grout evaluation for the extension of the Blue Metro Line

    University essay from KTH/Jord- och bergmekanik

    Author : Roaa Al Omari; Yasmeen Alali; [2021]
    Keywords : ;

    Abstract : This thesis forms the basis for a new documented experience of grouting design and work in the extension of the blue metro line in Stockholm. It includes documentation of the grouting design based on theoretical basis, stop criteria and fan geometries for favorable and unfavorable geological conditions. READ MORE

  3. 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.

  4. 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

  5. 5. 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.
