Calcined Clay as Supplementary Cementitious Material. [PDF]

Materials (Basel), 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 ...

Investigations into Replacing Calcined Clay with Sewage Sludge Ash in Limestone Calcined Clay Cement (LC3). [PDF]

Materials (Basel)
The effects of replacing calcined clay with sewage sludge ash (SSA) treated under room temperature and high temperature ranging from 500 °C to 900 °C in limestone calcined clay cement (LC3) have been investigated in this paper. The optimal calcination temperature for SSA was found to be 800 °C based on the results of strength and microstructure ...

Performance of Limestone Calcined Clay Cement (Lc3) Incorporating Low-Grade Marine Clay

Case Studies in Construction Materials, 2023
Clay is a globally abundant material and can potentially be used as a cement substitute after calcination. Though kaolinitic clay exhibits notable reactivity, the potential of low-grade clay with relatively low kaolinite content remains underexplored.

Preliminary exploration of the hydration-carbonation coupling mechanism of low-carbon calcined clay-carbide slag-cement composites

Journal of CO2 Utilization
To reduce the environmental impact of cement production and carbon emissions, the use of supplementary cementitious materials to replace part of the clinker and carbonation curing are two of the most effective strategies for reducing carbon dioxide ...

Color control in industrial clay calcination

RILEM Technical Letters, 2020
The combined use of calcined clays and limestone in the ternary system LC3 enables up to 50% of clinker substitution without affecting the performance. Low grade calcined clays are rich in iron. If calcined in an oxygen rich atmosphere, they turn to red.

Impact of calcination technology on properties of calcined clays

RILEM Technical Letters
Calcined kaolinitic clays are known to be very reactive pozzolans, and combined with limestone can enable significant clinker substitution in cementitious systems.
