Proceedings pro068 : 3rd International Symposium on Rheology of Cement Suspensions such as Fresh Concrete

Title: 3rd International Symposium on Rheology of Cement Suspensions such as Fresh Concrete Edited by O. H. Wallevik, S. Kubens and S. Oesterheld ISBN: 978-2-35158-091-2 e-ISBN: 978-2-35158-092-9 Pages: 372 Publication date: 2009

This 3rd International Symposium on Rheology of Cement Suspensions such as Fresch Concrete is held together with the 18th Nordic Rheology Conference on Suspensions and Emulsions.

The development of rheology of cement based materials has been substantial during the last decade, as the building industry has welcomed it to be a long needed solution for different conditions. New materials and admixtures, which influence the rheological properties, are constantly emerging on the market.

The sessions of the symposium deals with the following main topics:
- Cement suspensions
- Self-compacting concrete (SCC)
- Models and Simulation
- Chemical admixtures
- SCC - aggregate and filler
- Measurement technique
- Fibre-reinforced concrete and SCC
