  3. 17. Designing Roller compacted concrete (RCC) dams

    University essay from KTH/Betongbyggnad

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

    Abstract : 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. READ MORE

  4. 18. Finite element analysis of temperature in hardening concrete using isothermal calorimetric data

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : John Mac; [2017]
    Keywords : isoconversion; isothermal calorimetry; thermal analysis; finite element method; numerical simulation; Technology and Engineering;

    Abstract : The produced heat in hardening concrete is of special importance to consider as the temperature rise within a large concrete structure can become such high that the structure may experience thermal cracking. With use of a simulation program that is based on the finite element method, the temperatures within the structure can be estimated to predict possible crack development. READ MORE

  5. 19. Thermal cracking of a concrete arch dam due to seasonal temperature variations

    University essay from KTH/Betongbyggnad

    Author : Jonas Enzell; Markus Tollsten; [2017]
    Keywords : Arch dam; Concrete; Finite element analysis; Cracking; Progressive failure analysis; Valvdamm; Betong; Finit elementanalys; Sprickor; Progressiv brottanalys;

    Abstract : Concrete dams located in northern regions are exposed to large seasonal temperature variations. These seasonal temperature variations have resulted in cracking in thin concrete dams. Continuous monitoring and evaluation of existing dams are important to increase the knowledge about massive concrete structures and to ensure dam safety. READ MORE

  6. 20. Temperature reduction during concrete hydration in massive structures

    University essay from KTH/Betongbyggnad

    Author : Sandra Lagundzija; Marie Thiam; [2017]
    Keywords : Massive concrete structures; hydration heat; temperature reduction; crack risk; mineral additions; concrete cooling; Massiva betongkonstruktioner; värmeutveckling; temperaturreducering; sprickbildning; mineraltillsatser; kylning av betong;

    Abstract : Concrete is one of the most used building materials in the world because of its good properties. However, cement which is one of the main components in concrete, produces a high amount of heat during the hydration process. The generated heat leads to temperature rise inside the structure.
