  7. 5. Temperature reduction during concrete hydration in massive structures

    Master-uppsats, KTH/Betongbyggnad

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

    Sammanfattning : 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. LÄS MER
