Course content

The subject gives state-of-the-art within the areas:
1) chemical and physical micro-structure and pore structure in hardened cement paste, 3) the role of water as a part of the structure, as well as in adsorbed state and as pore water, 3) the structure of the transition zone between aggregate and paste.
The effect of binder composition and type of aggregate on the various properties are delt with.
Methods to determine micro-structure, pore structure and error structure (inhomogenities, cracks, etc) are covered.
The relation between micro- and pore structure and central service properties as volume stability, moisture transport and durability are treated.
The use of silica fume and high amounts of admixtures in high strength concretes will be emphasized. The course can be adapted to individual research interests within concrete technology.

Learning outcome

To give an understanding of physichal mechanisms in the solid and porous structure of concrete that affects and controls the macroscopic properties of concrete materials (strength, volume stability, transport, durability) including the significance of water.

Learning methods and activities

The course will be based partly on lectures and partly as colloquium. The lectures and exercises are in English when students who do not speak Norwegian take the course.
