  3. 17. Evaluation of air entraining behaviour in concrete using computer aided methods on hardened samples

    University essay from KTH/Betongbyggnad

    Author : Jakub Pawlowicz; [2019]
    Keywords : concrete; air voids; air entraining; AEA; blast furnace slag; BFS; flat-bed scanner; BubbleCounter; traverse method;

    Abstract : Increasing awareness of sustainability in the concrete industry forces structural design and executionto focus on avoiding costly and unpredictable maintenance action, instead paying higher attention todamage prevention by direct actions on early stages of production. One of such approaches, whichdeals with the problem of freezing and thawing deterioration, is intentional air bubble introductionto the concrete mix. READ MORE

  5. 19. Principles for tuning heat zone controllers in a belt furnace through modeling and simulation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Henrik Fryklund; [2018]
    Keywords : Technology and Engineering;

    Abstract : In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. READ MORE
