Calcined Clay - an overview | ScienceDirect Topics
Calcined clay is a material obtained from processing clayey material with sufficient mechanical strength for a particular purpose. Once the clay is calcined (burned at high temperatures >760 °C), it develops new properties allowing it to be used as SCMs.

Calcined clay – or metakaolin – is produced by heating a source of kaolinite to between 650°C and 750°C. Kaolin is both naturally occurring, as in china clay deposits and some tropical soils, as well as in industrial by-products, such as some paper sludge waste and oil sands tailings.
Calcined Clay as Supplementary Cementitious Material - PMC
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.
Lower-Carbon Cement Called LC3 Is Promising, Experts Say
2023年7月12日 · Calcined clay, or metakaolin, is produced by heating a source of low-grade kaolinite clay to between 650° C and 750° C. Both limestone and low-grade clays are available in abundant quantities,...

Calcined clays are one the materials that are classed as “natural calcined pozzolana” in the European standard for cement, EN 197-1. This allows cement producers to make a range of cements with up to 55% of the Portland cement clinker replaced by calcined clay.
most typical Limestone Calcined Clay Cement (LC3) as an example, compared to Portland cement, the clinker content of LC 3 can be reduced up to 50% by adding limestone and calcined clay.
production of calcined clays, presents an overview of clay mining, and assesses the current state of the art in clay calcination technology, covering the most relevant aspects from the clay deposit to the factory gate.
