Supplementary cementitious materials

Cement and Concrete Research, 2011
Abstract The use of silica rich SCMs influences the amount and kind of hydrates formed and thus the volume, the porosity and finally the durability of these materials. At the levels of substitution normally used, major changes are the lower Ca/Si ratio in the C–S–H phase and consumption of portlandite.

Calcined Palygorskites as Supplementary Cementitious Materials

Clays and Clay Minerals, 2022
AbstractReducing the environmental footprint of cement is an absolute necessity to meet the commitments of COP26 and to limit global warming to + 1.5°C compared to the pre-industrial level. In this context, particular interest has developed in recent years in the use of calcined clays as supplementary cementitious materials (SCMs).

Supplementary Cementitious Materials

Reviews in Mineralogy and Geochemistry, 2012
The current widespread use of calcium silicate or aluminate hydrate binder systems in the construction industry finds its roots in the Antique world where mixtures of calcined lime and finely ground reactive (alumino-)silicate materials were pioneered and developed as competent inorganic binders.

Feasibility of low-carbon electrolytic manganese residue-based supplementary cementitious materials.

Science of the Total Environment, 2023
In this work, the electrolytic manganese residues (EMR) were used as sulfate activators for fly ash and granulated blast-furnace slag to fabricate highly reactive supplementary cementitious materials (SCMs).

Metakaolin as supplementary cementitious material

Journal of Thermal Analysis and Calorimetry, 2005
In this paper the optimization of the kaolin calcination is studied, aiming at using the produced metakaolin as supplementary cementitious material. Representative samples of poor Greek kaolin (Milos island) and a high purity commercial kaolin were tested. Samples were heated at different temperatures during different times.
