3. 2. Thermal stresses in concrete structures at early ages

   Författare :Mats Emborg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : This thesis deals with the problem of formulating constitutive models for the analysis of early-age thermal stresses in concrete due to hydration. The main features of the work are constitutive modelling of early-age concrete behaviour experimental studies to check the models and to determine material parameters application of the models to some design and construction situations.

4. 3. Concrete as a multi-physical material with applications to hydro power facilities

   Författare :Tobias Gasch; Anders Ansell; Richard Malm; Erik Nordström; Mats Emborg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : During its lifetime, a concrete structure is subjected to many different actions, ranging from mechanical loads to environmental actions. To accurately predict its integrity from casting and throughout its service life, a modelling strategy is required that considers mechanical loading but also implicitly accounts for physical effects such as temperature and moisture variations.

5. 4. Aggregates in Concrete Mix Design

   Författare :Yahya Ghasemi; Mats Emborg; Andrzej Cwirzen; Martin Nilsson; Gram Hans-Erik; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mix design; water layer theory; particle packing; aggregates; specific surface area; Byggproduktion; Construction Engineering and Management;

   Sammanfattning : The importance of studying the behaviour and properties of concrete can be highlighted by considering the fact that concrete is the most used man-made material in the world. The very first step in making concrete is its mix design and deciding the type and amount of constitutes used in the production of concrete which should fulfil the requirements of the final product.

7. 5. Flowability and proportioning of cementitious mixtures

   Författare :Yahya Ghasemi; Mats Emborg; Andrzej Cwirzen; Martin Nilsson; Stefan Jacobsen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle packing; excess layer theory; mix design; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : Understanding the role of constituents of cementitious mixtures as the most globally used human-made material and their effect on the flowability of the blends is of great importance. A comprehensive understanding of the ingredients of mixtures allows for optimized proportioning of constituents and can lead to a reduction in cement and water demand of the blends. LÄS MER
