  1. 1. Optimization of the steel-fiber dosage in shotcrete used in the Kankberg mine

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Pontus Larsson; [2018]
    Keywords : rock mechanics; shotcrete; bergmekanik; sprutbetong;

    Abstract : The Swedish metal company Boliden has since the early 20th century been mining deposits in the mining field commonly referred to as the Skelleftefield in northern Sweden. The youngest of the active mines is the Kankberg mine which is an underground mine whose reserve contains gold and tellurium. READ MORE

  2. 2. An experimental study of the validity of the round panel test method for shotcrete

    University essay from KTH/Betongbyggnad

    Author : Nadia El zain; [2018]
    Keywords : Shotcrete; sprayed concrete; yield line theory; tunnel lining; steel fibers; round determinate panels; test beams; Sprutbetong; runda plattor; tunnelbeklädnad; fiberarmerad sprutbetong; stålfibrer; böjdraghållfasthet; balkar; mätosäkerhet;

    Abstract : Shotcrete (sprayed concrete) was used for the first time in 1914 and has become of  growing importance in stabilizing the excavated tunnel sections over the past century.  Even though the technology develops, there are some difficult tasks such as the design of a bolt anchored tunnel lining made of shotcrete.

  3. 3. Spatial Variability of shotcrete thickness

    University essay from KTH/Jord- och bergmekanik

    Author : Maximilian Klaube; [2018]
    Keywords : Spatial variability; Scale of fluctuation; Correlogram; Tunnel;

    Abstract : An  important  task   during  the  construction  process  is  to  validate  the dimensions  and  properties  of  a  given  structure.  The  dimensions  like  for instance the thickness of a construction element should  be measured after finishing  building  it. READ MORE

  4. 4. Reinforced Concrete Beams Strengthened with Side Near Surface Mounted FRP : A parametric study based on finite element analysis

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Rewan Eredini; [2016]
    Keywords : Side near surface mounted reinforcement; Bottom near surface mounted reinforcement; Parametric study; FEM-analysis; Atena; Carbon fiber reinforced polymer;

    Abstract : Most of the today’s concrete structures are older than tenyears, and the need to strengthening existing structures is growing steadily. This is due to various reasons such as degradation due to ageing, environmentally induced degradation, poor initial design or construction and lack of maintenance, to name a few. READ MORE

  5. 5. Punching Shear Capacity of Fibre Reinforced Concrete Slabs with Conventional Reinforcement : Computational analysis of punching models

    University essay from KTH/Bro- och stålbyggnad

    Author : Zeinab Tazaly; [2012]
    Keywords : Steel fibre reinforced concrete slab; punching capacity; concrete test; residual tensile strength; DAfStB; Swedish Concrete Association; conventional reinforcement;

    Abstract : Steel fibre reinforced concrete is not a novel concept, it has been around since the mid-1900s, but despite its great success in shotcrete-reinforced rock walls and industrial floors it has not made any impact on either beams or elevated slab. Apparently, the absence of standards is the main reason. READ MORE
