  4. 13. 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.

  5. 14. Kalciumomsättning och kalciumreglering : en jämförelse mellan värphöns och mjölkkor

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Kajsa Lätt; [2017]
    Keywords : Kalciumbrist; Kalcium; Medullärben; Kalvningsförlamning;

    Abstract : Kalciumbrist är ett kostsamt tillstånd för produktionen. När värphöns drabbas av kalcium-brist försämras skalkvaliteten på äggen och tillslut avtar äggproduktionen. Mjölkkor drabbas oftast av akut kalciumbrist före eller efter kalvning, vilket ofta leder till höga veterinärkost-nader och kan även orsaka andra sjukdomar. READ MORE
