Scientific Committee
Background
Due to its high porosity and internal surface concrete is intensively interacting with its environment, affecting the properties and long term behaviour.
Taking this into account, the transport of vapour, liquid water and dis-solved matter and their interaction with the solid matrix as well as the reinforcement is most important. Transport and the exchange of matter modify both the mechanical properties and the durability. Heat trans-port and temperature gradients are further important parameters. In general, the driving forces for the transport are temperature and concentration gradients, suction effects, frost action and electrical fields.
The amount of transport is affected by the porous structure of con-crete especially the pore size distribution. In addition, it has to be con-sidered that the transport mechanisms in the nano or gel structure is basically different from the transport in the macro structure since the nanoscopic properties are highly dominated by surface physics and chemistry. At the same time, the durability and mechanical properties of the structure are differently affected by surface physics and chem-istry and by macroscopic bulk physics and chemistry. It only depends on the scale which natural laws are dominant – the surface interaction or the macroscopic bulk effects. The description and modelling must be adopted to this.
The aim of the workshop is to bridge the different aspects necessary for an appropriate description of concrete properties and long term performance: from application to basic science, from surface science to macroscopic effects, from physical to chemical effects, from model-ling to phenomenological experience, from concrete matrix to rein-forcement.
The workshop is intended as a continuation of the Bolomey workshop on “Pore Solution in hardened Cement Paste” held in Essen 1998, the two workshops on “Frost Action” held in 1997, 2002 as well as the workshop on “Durability of High Performance Concrete and final Workshop of CONLIFE” in 2004 (4th International Essen workshop).
