Optimization of SEM-EDS to determine the C-A-S-H composition in matured cement paste samples

Microanalysis of characteristic X-rays in the SEM is a powerful method to assess the chemical composition of phases in cement pastes, in particular the calcium silicate hydrate containing aluminium (C-A-S-H). Nevertheless, many variables may influence the ...

Composition of C-S-H in pastes with increasing levels of silica fume addition

Karen Scrivener, John Espen Rossen, Barbara Lothenbach

New results show that the microstructure development of cement–silica fume blends is very different from plain cement. Portlandite (CH) tends to precipitate as platelets and even around clinker grains as “CH rims” and is consumed by pozzolanic reaction wit ...

Cement substitution by a combination of metakaolin and limestone

Karen Scrivener, Mathieu Antoni, John Espen Rossen

This study investigates the coupled substitution of metakaolin and limestone in Portland cement (PC). The mechanical properties were studied in mortars and the microstructural development in pastes by X-ray diffraction, thermogravimetry analysis, mercury i ...
