It is commonly known that the age of cement or inadequate storage can result in different engineering properties of concrete or mortar. In a pre-study, the general phenomenon of prehydration of cement was scientifically investigated in a Nanocem MSc project started in 2007. With "cement prehydration" we mean the interaction between cement and water vapour. In our studies it was possible to reproduce the field problems in the lab and to research the causes by using modern analytical tools.
Currently, the knowledge of very early cement hydration and related analytical methods is still limited. Prehydration of cement is a surface process, whereby only a few methods like XPS and FTIR-ATR spectroscopy can be utilised.
The aim of NANOCEM Core Project 7 is to fill this gap by the enhancement of the current methods and to develop new analytical strategies for surface analysis. Also, we will probe deeper into the prehydration processes on the cement grain surface; and subsequently the related consequences for the bulk cement.
