Modeling of Chloride Binding Capacity in Cementitious Matrices Including Supplementary Cementitious Materials

Crystals, 2022
The improvement in the chloride binding capacity of concrete has been shown to increase corrosion resistance. The addition of supplementary cementitious materials (SCMs) to Portland cement has been proven to increase the binding capacity, except for ...

Calcined Clay as Supplementary Cementitious Material [PDF]

Materials, 2020
Calcined clays are the only potential materials available in large quantities to meet the requirements of eco-efficient cement-based materials by reducing the clinker content in blended cements or reducing the cement content in concrete. More than 200 recent research papers on the idea of replacing Portland cement with large amounts of calcined clay ...

Carbonated wollastonite – An effective supplementary cementitious material? [PDF]

Journal of Microscopy, 2021
AbstractCarbonated wollastonite clinker (CS) may be suitable as supplementary cementitious material (SCM) for mortar and concrete. The microstructure of unground CS clinker, carbonated CS slurry and a mortar blended with carbonated CS are investigated by scanning electron microscopy.
