Dealing with uncertainty in material characterization of concrete by education

In this article a trip is taken to characterize concrete through its hardened cement paste based on its microstructure. Optical microscopy is coupled to advanced image analysis, as well as statistical data analysis to characterize heterogeneous concrete material. The article takes a closer look at the determination of the w/c ratio through the...

Revealing the dark side of Portlandite Clusters in cement paste by circular polarization microscopy

Plane and crossed polarization are the two standard light modes in polarized light microscopy that are widely used to characterize crystalline and amorphous phases in cement-based materials. However, the use of the crossed polarized light mode has been found to be restrictive for studying birefringent phases quantitatively due to the extinction...
