  1. 1. BETONG OCH BRANDSPJÄLKNING : Aktuella lösningar för brandspjälkning

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Efrem Beraki; Fitwi Russom; [2021]
    Nyckelord :;

    Sammanfattning : Dense, damp concrete structures can be damaged by fire. Concrete spalling in the event of a fire causes serious damage to concrete structures, which entails significant economic conse-quences as well as the risk of putting human life at risk. LÄS MER

  3. 2. Prediction of early age and time dependent deformations in a massive concrete structure

    Master-uppsats, KTH/Betongbyggnad

    Författare :Ali Aghili; Haris Ribac; [2018]
    Nyckelord :Early age concrete; hydration of cement; Storfinnforsen; ConTeSt; crack risk; temperature development; strain; mass concrete structures; measurement plan; Ung betong; hydratation av cement; Storfinnforsens kraftverk; ConTeSt; sprickrisk; temperatur; töjning; massiva konstruktioner; mätningsplanering;

    Sammanfattning : The heat development that occurs due to the hydration of cement is important to consider during casting of massive concrete structures. By using computer programs that are based on finite element methods (FEM), simulations can be performed on the heat- and strength development. LÄS MER

  5. 4. Designing Roller compacted concrete (RCC) dams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Shayma Al Baghdady; Linnea Khan; [2018]
    Nyckelord :Roller Compacted concrete; Massive concrete structures; Dams; Concrete;

    Sammanfattning : Concrete is the most common building material in the world and it consists of aggregates,cement and water that harden over time, it is also known as a composite material. The use ofconcrete is very versatile due to its resistance to wind and water and its ability to withstandhigh temperature. LÄS MER

  7. 5. The Effects of Erosion-control Structures and Gully Erosion on Groundwater Dynamics Along the Kromrivier, Eastern Cape, South Africa

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Vincent de Haan; [2016]
    Nyckelord :Gully erosion; wetland; groundwater dynamics; erosion-control structures;

    Sammanfattning : The Palmiet wetlands located along the Kromrivier in the Eastern Cape province of South Africa have experienced severe degradation through gully erosion during the past decennia which has been threatening the water quality and water security of large towns in the Nelson Mandela Metropolitan hub. Water scarcity is a growing problem in this region as a result of land degradation and growing erratic rainfall patterns. LÄS MER
